Efficient recombinant production of mouse-derived cryptdin family peptides by a novel facilitation strategy for inclusion body formation. Microb Cell Fact 2023; 22:9.

Abstract
BACKGROUND A number of antimicrobial peptides (AMPs) hold promise as new drugs owing to their potent bactericidal activity and because they are often refractory to the development of drug resistance. Cryptdins (Crps) are a family of antimicrobial peptides found in the small intestine of mice, comprising six isoforms containing three sets of disulfide bonds. Although Crp4 is actively being investigated, there have been few studies to date on the other Crp isoforms. A prerequisite for detailed characterization of the other Crp isoforms is establishment of efficient sample preparation methods. RESULTS To avoid degradation during recombinant expression of Crps in E. coli, co-expression of Crps with the aggregation-prone protein human α-lactalbumin (HLA) was used to promote the formation of stable inclusion bodies. Using this method, the production of Crp4 and Crp6 by the BL21 strain was effective, but the expression of other Crp isoforms was not as efficient. The results of a cell-free system study suggested that Crps were degraded, even though a substantial amounts of Crps were synthesized. Therefore, using the Origami™ B strain, we were able to significantly increase the expression efficiency of Crps by promoting the formation of erroneous intermolecular disulfide bonds between HLA and Crps, thereby promoting protein aggregation and inclusion body formation, which prevented degradation. The various Crp isoforms were successfully refolded in vitro and purified using reversed-phase HPLC. In addition, the yield was further improved by deformylation of formyl-Crps. We measured the antibacterial activity of Crps against both Gram-positive and Gram-negative bacteria. Each Crp isoform exhibited a completely different trend in antimicrobial activity, although conformational analysis by circular dichroism did not reveal any significant steric differences. CONCLUSION In this study, we established a novel and efficient method for the production of the cryptdin family of cysteine-containing antimicrobial peptides. Additionally, we found that there were notable differences in the antibacterial activities of the various Crp family members. The expression system established in this study is expected to provide new insights regarding the mechanisms underlying the different antibacterial activities of the Crp family of peptides.

Abstract
The antimicrobial resistance crisis calls for the discovery and production of new antimicrobials. Host defense peptides (HDPs) are small proteins with potent antibacterial and immunomodulatory activities that are attractive for translational applications, with several already under clinical trials. Traditionally, antimicrobial peptides have been produced by chemical synthesis, which is expensive and requires the use of toxic reagents, hindering the large-scale development of HDPs. Alternatively, HDPs can be produced recombinantly to overcome these limitations. Their antimicrobial nature, however, can make them toxic to the hosts of recombinant production. In this review we explore the different strategies that are used to fine-tune their activities, bioengineer them, and optimize the recombinant production of HDPs in various cell factories.

Abstract
Background Difficult to express peptides are usually produced by co-expression with fusion partners. In this case, a significant mass part of the recombinant product falls on the subsequently removed fusion partner. On the other hand, multimerization of peptides is known to improve its proteolytic stability in E. coli due to the inclusion of body formation, which is sequence specific. Thereby, the peptide itself may serve as a fusion partner and one may produce more than one mole of the desired product per mole of fusion protein. This paper proposes a method for multimeric production of a human alpha-fetoprotein fragment with optimized multimer design and processing. This fragment may further find its application in the cytotoxic drug delivery field or as an inhibitor of endogenous alpha-fetoprotein. Results Multimerization of the extended alpha-fetoprotein receptor-binding peptide improved its stability in E. coli, and pentamer was found to be the largest stable with the highest expression level. As high as 10 aspartate-proline bonds used to separate peptide repeats were easily hydrolyzed in optimized formic acid-based conditions with 100% multimer conversion. The major product was represented by unaltered functional alpha-fetoprotein fragment while most side-products were its formyl-Pro, formyl-Tyr, and formyl-Lys derivatives. Single-step semi-preparative RP-HPLC was enough to separate unaltered peptide from the hydrolysis mixture. Conclusions A recombinant peptide derived from human alpha-fetoprotein can be produced via multimerization with subsequent formic acid hydrolysis and RP-HPLC purification. The reported procedure is characterized by the lower reagent cost in comparison with enzymatic hydrolysis of peptide fusions and solid-phase synthesis. This method may be adopted for different peptide expression, especially with low amino and hydroxy side chain content.

Abstract
The antimicrobial peptide PMAP-36 is a cationic peptide derived from porcine myeloid. The N-terminally paired lysine of PMAP-36 was substituted with tryptophan, and the C-terminal hydrophobic tail was deleted, thereby obtaining the antimicrobial peptide PRW4. PRW4 is a α-helical antimicrobial peptide with broad-spectrum antimicrobial activity. In this study, PRW4 was fused to the 6× His-Trx, and the fusion protein was successfully expressed in Pichia pastoris GS115 from the vector pPICZαA. The maximal induction of recombinant protein occurred in the presence of 1% methanol after 96 h at pH 6.0. After purification by a Ni-NTA resin column and digestion by enterokinase protease, 15 mg of recombinant PRW4 with a purity of 90% was obtained from 1 L of fermentation culture. The results indicated that recombinant PRW4 had similar antimicrobial activity as synthetic PRW4 against bacteria such as Escherichia coli ATCC 25922, Escherichia coli UB 1005, Salmonella typhimurium C7731, Salmonella typhimurium 7913, Salmonella typhimurium ATCC 14028, Staphylococcus aureus ATCC 29213, Staphylococcus epidermidis ATCC 12228, and Streptococcus faecalis ATCC 29212. We have successfully expressed PRW4 in P. pastoris, and this work provides a reference for the production of modified antimicrobial peptides in P. pastoris.

Abstract
A DNA fragment amplification/expression technology for the production of new generation biomaterials for scientific, industrial and biomedical applications is described. The technology enables the formation of artificial Open Reading Frames (ORFs) encoding concatemeric RNAs and proteins. It recruits the Type IIS SapI restriction endonuclease (REase) for an assembling of DNA fragments in an ordered head-to-tail-orientation. The technology employs a vector-enzymatic system, dedicated to the expression of newly formed, concatemeric ORFs from strong promoters. Four vector series were constructed to suit specialised needs. As a proof of concept, a model amplification of a 7-amino acid (aa) epitope from the S protein of HBV virus was performed, resulting in 500 copies of the epitope-coding DNA segment, consecutively linked and expressed in Escherichia coli (E. coli). Furthermore, a peptide with potential pro-regenerative properties (derived from an angiopoietin-related growth factor) was designed. Its aa sequence was back-translated, codon usage optimized and synthesized as a continuous ORF 10-mer. The 10-mer was cloned into the amplification vector, enabling the N-terminal fusion and multiplication of the encoded protein with MalE signal sequence. The obtained genes were expressed, and the proteins were purified. Conclusively, we show that the proteins are neither cytotoxic nor immunogenic and they have a very low allergic potential.

Abstract
The efficient production of antimicrobial peptides (AMPs) for clinical applications has attracted the attention of the scientific community. To develop a novel microbial cell factory for the efficient biosynthesis of a cecropin A-melittin mutant (CAM-W), a recombinant Bacillus subtilis WB700 expression system was genetically modified with a novel vector, including a fusion gene encoding CAM-W, the autoprotease EDDIE and the signal peptide SacB under the control of the maltose-inducible promoter Pglv. A total of 159 mg of CAM-W was obtained from 1 L of fermentation supernatant. The purified CAM-W showed a consistent size with the expected molecular weight of 3.2 kDa. Our findings suggest that this novel expression system can be used as a powerful tool for the efficient production of CAM-W.

Abstract
Vessel dilator is a 3.9-KDa potent anticancer peptide and a valuable candidate in the treatment of conditions such as congestive heart failure and acute renal failure amongst others. Here we report the recombinant production of vessel dilator in Escherichia coli. Three different synthetic ORF's dubbed VDI, VDII and VDIII, each encoding a trimmer of the vessel dilator peptide attached to a His tag sequence at their C- terminal, were synthesized and placed in pET21c expression vectors. The highest yield, following expression in E. coli BL21 (DE3), was recorded with VDII that carried the shortest fusion partner. Subsequent to the initial capture of the fusion protein by a Ni affinity column, the vessel dilator monomers were cleaved by trypsin treatment, and further purified to at least 90% homogeneity by anion exchange chromatography. De-novo sequencing and in vivo anticancer activity tests were used to verify the peptide sequence and its biological activity, respectively. The final yield was estimated to be approximately 15 mg of the purified vessel dilator per gram wet weight of the bacterial cells.

Abstract
An integrative food-grade expression system with tandem repeat target genes was constructed for the expression of d-psicose 3-epimerase (DPEase; EC 5.1.3.30). The DPEase gene fused with the P43 promoter constituted an independent monomeric expression cassette. Multimers of the expression cassette were constructed in vitro using the isocaudamer strategy. The recombinant integration plasmids pDG-nDPE (n = 1, 2, 3), which contained one, two, or three consecutive P43-DPEase tandem repeats, were integrated into the genome of B. subtilis. Then, the antibiotic resistance gene was deleted by the Cre/lox system, and the food-grade recombinant B. subtilis 1A751-nDPE (n = 1, 2, 3) with integrated tandem repeats of the P43-DPEase expression cassette were generated. The specific activity of the B. subtilis 1A751-3DPE was the highest among the recombinant strains and was ∼2.2-fold that of the 1A751-1DPE strain. Under the optimal conditions, 8 g/L of freeze-dried enzyme powder could convert 20% d-fructose (300 g/L) into d-allulose after 1 h.

Green fluorescent protein as a scaffold for high efficiency production of functional bacteriotoxic proteins in Escherichia coli. Sci Rep 2016; 6:20661.

Abstract
The availability of simple, robust, and cost-effective methods for the large-scale production of bacteriotoxic peptides such as antimicrobial peptides (AMPs) is essential for basic and pharmaceutical research. However, the production of bacteriotoxic proteins has been difficult due to a high degree of toxicity in bacteria and proteolytic degradation. In this study, we inserted AMPs into the Green fluorescent protein (GFP) in a loop region and expressed them as insoluble proteins in high yield, circumventing the inherent toxicity of AMP production in Escherichia coli. The AMPs inserted were released by cyanogen bromide and purified by chromatography. We showed that highly potent AMPs such as Protegrin-1, PMAP-36, Buforin-2, and Bactridin-1 are produced in high yields and produced AMPs showed similar activities compared to chemically synthesized AMPs. We increased the yield more than two-fold by inserting three copies of Protegrin-1 in the GFP scaffold. The immunogold electron micrographs showed that the expressed Protegrin-1 in the GFP scaffold forms large and small size aggregates in the core region of the inclusion body and become entirely nonfunctional, therefore not influencing the proliferation of E. coli. Our novel method will be applicable for diverse bacteriotoxic peptides which can be exploited in biomedical and pharmaceutical researches.

Abstract
Antimicrobial peptides (AMPs) are small molecules which serve as essential components of the innate immune system in various organisms. AMPs possess a broad spectrum of antimicrobial activities. However, the scaled production of such peptides in Escherichia coli faces many difficulties because of their small size and toxicity to the host. Here, we described a new fusion strategy to extracellularly produce significant amounts of these antimicrobial peptides in recombinant E. coli at significant amount. Employing the catalytic domain of a cellulase (Cel-CD) from Bacillus subtilis KSM-64 as the fusion partner, five recombinant antimicrobial peptides were confirmed to accumulate in the culture medium at concentrations ranging from 184 mg/L to 297 mg/L. The radical diffusion experiment demonstrated that the released model antimicrobial peptide, bombinin, had antibacterial activities against both E. coli and Staphylococcus aureus. This strategy will be suitable for the production of antimicrobial peptides and other toxicity proteins.

Abstract
Antimicrobial peptides (AMPs) are part of the innate immune system of complex multicellular organisms. Despite the fact that AMPs show great potential as a novel class of antibiotics, the lack of a cost-effective means for their mass production limits both basic research and clinical use. In this work, we describe a novel expression system for the production of antimicrobial peptides in Escherichia coli by combining ΔI-CM mini-intein with the self-assembling amphipathic peptide 18A to drive the formation of active aggregates. Two AMPs, human β-defensin 2 and LL-37, were fused to the self-cleaving tag and expressed as active protein aggregates. The active aggregates were recovered by centrifugation and the intact antimicrobial peptides were released into solution by an intein-mediated cleavage reaction in cleaving buffer (phosphate-buffered saline supplemented with 40 mmol/L Bis–Tris, 2 mmol/L EDTA, pH 6.2). The peptides were further purified by cation-exchange chromatography. Peptides yields of 0.82 ± 0.24 and 0.59 ± 0.11 mg/L were achieved for human β-defensin 2 and LL-37, respectively, with demonstrated antimicrobial activity. Using our expression system, intact antimicrobial peptides were recovered by simple centrifugation from active protein aggregates after the intein-mediated cleavage reaction. Thus, we provide an economical and efficient way to produce intact antimicrobial peptides in E. coli.

Abstract
Antimicrobial agents have eradicated many infectious diseases and significantly improved our living environment. However, abuse of antimicrobial agents has accelerated the emergence of multidrug-resistant microorganisms, and there is an urgent need for novel antibiotics. Antimicrobial peptides (AMPs) have attracted attention as a novel class of antimicrobial agents because AMPs efficiently kill a wide range of species, including bacteria, fungi, and viruses, via a novel mechanism of action. In addition, they are effective against pathogens that are resistant to almost all conventional antibiotics. AMPs have promising properties; they directly disrupt the functions of cellular membranes and nucleic acids, and the rate of appearance of AMP-resistant strains is very low. However, as pharmaceuticals, AMPs exhibit unfavorable properties, such as instability, hemolytic activity, high cost of production, salt sensitivity, and a broad spectrum of activity. Therefore, it is vital to improve these properties to develop novel AMP treatments. Here, we have reviewed the basic biochemical properties of AMPs and the recent strategies used to modulate these properties of AMPs to enhance their safety.

Abstract
Antimicrobial peptides (AMPs) consist of molecules that act on the defense systems of numerous organisms toward multiple pathogens such as bacteria, fungi, parasites and viruses. These compounds have become extremely significant due to the increasing resistance of microorganisms to common antibiotics. However, the low quantity of peptides obtained from direct purification is, to date, still a remarkable bottleneck for scientific and industrial research development. Therefore, this review describes the main heterologous systems currently used for AMP production, including bacteria, fungi and plants, and also the related strategies for reaching greater functional peptide production. The main difficulties of each system are also described in order to provide some directions for AMP production. In summary, data revised here indicate that large-scale production of AMPs can be obtained using biotechnological tools, and the products may be applied in the pharmaceutical industry as well as in agribusiness.

Abstract
The coding sequence, which corresponds to the mature antimicrobial peptide ranalexin from the frog Rana catesbeiana, was chemically synthesized with preferred codons for expression in Escherichia coli. It was cloned into the vector pET32c (+) to express a thioredoxin-ranalexin fusion protein which was produced in soluble form in E. coli BL21 (DE3) induced under optimized conditions. After two purification steps through affinity chromatography, about 1 mg of the recombinant ranalexin was obtained from 1 L of culture. Mass spectrometrical analysis of the purified recombinant ranalexin demonstrated its identity with ranalexin. The purified recombinant ranalexin is biologically active. It showed antibacterial activities similar to those of the native peptide against Staphylococcus aureus, Streptococcus pyogenes, E. coli, and multidrug-resistant strains of S. aureus with minimum inhibitory concentration values between 8 and 128 μg/ml. The recombinant ranalexin is also cytotoxic in HeLa and COS7 human cancer cells (IC50 = 13-15 μg/ml).

Abstract
To produce more angiotensin converting enzyme inhibitory peptides (ACEIP), we have established a high-efficiency Escherichia coli expression system. The DNA-coding sequence for the recombinant protein, which was subcloned into the vector pET-30a(+), has been expressed as inclusion bodies in E. coli BL21 (DE3). The influences of induction time and concentration of isopropyl-β-D-thiogalactopyranoside (IPTG) on the expression of recombinant protein were studied. The resulting expression level of the protein accounted for about 31% of cellular protein at a temperature of 37°C, IPTG concentration of 0.6mM and induction time of 7h. The inclusion bodies were washed, separated from the cells, and solubilized with urea. After purification by affinity chromatography, the recombinant protein was recovered with a high purity of about 90%. Molecular weight of the recombinant protein was measured using Tricine-SDS-PAGE. Peptide IYPR was obtained by cleavage of the recombinant protein with trypsin and the IC(50) value was 61 mg/L. The antihypertensive activity in spontaneously hypertensive rats (SHRs) was also investigated. Single oral administration of this peptide in 10-week old SHRs resulted in a significant reduction of systolic blood pressure to 50 mm Hg at 4 h. The data obtained provide a good reference for further development of peptide Ile-Tyr-Pro-Arg into an effective antihypertensive agent for prevention and treatment of hypertension.

Abstract
Buforin IIb is a novel cell-penetrating anticancer peptide derived from histone H2A. In this study, we enhanced the cancer targeting specificity of buforin IIb using a tumor-associated enzyme-controlled activation strategy. Buforin IIb was fused with an anionic peptide (modified magainin intervening sequence, MMIS), which neutralizes the positive charge of buforin IIb and thus renders it inactive, via a matrix metalloproteinases (MMPs)-cleavable linker. The resulting MMIS:buforin IIb fusion peptide was completely inactive against MMPs-nonproducing cells. However, when the fusion peptide was administrated to MMPs-producing cancer cells, it regained the killing activity by releasing free buforin IIb through MMPs-mediated cleavage. Moreover, the activity of the fusion peptide toward MMPs-producing cancer cells was significantly decreased when the cells were pretreated with a MMP inhibitor. Taken together, these data indicate that the cancer targeting specificity of MMIS:buforin IIb is enhanced compared to the parent peptide by reactivation at the specialized areas where MMPs are pathologically produced.

Abstract
As a potential therapeutic agent, antimicrobial peptide has received increased attention in recent years. However, high-level expression of a small peptide with antimicrobial activity is still a challenging task. In this study, the coding sequence of antimicrobial peptide hPAB-β, a variant derived from human beta-defensin 2, was cloned into pPIC9K vector and transformed into Pichia pastoris. P. pastoris transformants harbored with multi-copy plasmids were screened by G418 selection. When the transformed cells were induced by methanol, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Western blot, and matrix-assisted laser desorption ionization-time of flight mass spectrometry revealed recombinant hPAB-β products consisting of three protein species of 4,680.4, 4,485.3, and 4,881.9 Da at proportions of 58%, 36%, and 6%, respectively, which may be due to the incomplete processing of the fusion signal peptide of α-factor by the STE13 protease. Expressed hPAB-β was secreted into the culture medium at a level of 241.2 ± 29.5 mg/L. Purified hPAB-β with 95% homogeneity was obtained by 10 kDa membrane filtration followed by cation ion-exchange chromatography with a SP-Sepharose XL column. The two major protein species separated through a SOURCE 30RPC reverse phase chromatography column showed definite antimicrobial activities against Staphylococcus aureus. All 22 methicillin-resistant S. aureus (MRSA) isolates with multidrug resistance phenotype were sensitive to the recombinant hPAB-β with minimal inhibitory concentrations of 8-64 μg/ml. Our results show that the methylotrophic yeast-inducible system is suitable for high-level expression of active hPAB-β, and that expressed hPAB-β in P. pastoris may be a potential antimicrobial agent against MRSA infection.

Abstract
Human alpha-defensin 6 (HD(6)), a small cysteine-rich cationic peptide specially expressed in epithelial cells of digestive tract, may play a crucial role in mucosal immunity. This is the first report on efficient production of bioactive HD(6) through a gene-engineering approach in Escherichia coli. The recombinant plasmid pET32a-omHD(6) was primarily constructed by inserting a PCR fragment encoding mature HD(6) peptide (mHD(6)) preceded by an enterokinase recognition sequence into the expression vector pET32a(+), in frame with the upstream thioredoxin (TrxA) gene. Under optimized expression conditions, a high percentage (>60%) of soluble TrxA-omHD(6) fusion protein was obtained with a yield of about 1.69 g/l, and the theoretical productivity of recombinant mHD(6) (rmHD(6)) reached 0.38 g/l. A feasible three-step purification strategy involving nickel-sepharose chromatography, enterokinase-cleavage and cation exchange chromatography was developed to purify rmHD(6), followed by characteristic identifications by Western blot, mass spectrometry and sequencing. About 102 mg/l of rmHD(6) with its intact N-terminal amino acid sequence was finally achieved. The in vitro experiments showed that rmHD(6) possesses high potency to inhibit herpes simplex virus-2 infection. This work settles substantial foundation for further functional study of HD(6).

Abstract
Discovery of antimicrobial peptides (AMP) is to a large extent based on screening of fractions of natural samples in bacterial growth inhibition assays. However, the use of bacteria is not limited to screening for antimicrobial substances. In later steps, bioengineered "bugs" can be applied to both production and characterization of AMPs. Here we describe the idea to use genetically modified Escherichia coli strains for both these purposes. This approach allowed us to investigate SpStrongylocins 1 and 2 from the purple sea urchin Strongylocentrotus purpuratus only based on sequence information from a cDNA library and without previous direct isolation or chemical synthesis of these peptides. The recombinant peptides are proved active against all bacterial strains tested. An assay based on a recombinant E. coli sensor strain expressing insect luciferase, revealed that SpStrongylocins are not interfering with membrane integrity and are therefore likely to have intracellular targets.

Abstract
Antimicrobial peptides are an essential component of innate immunity and play an important role in host defence against microbial pathogens. They have received increasing attention recently as potential novel pharmaceutical agents. To meet the requirement for necessary basic science studies and clinical trials, large quantities of these peptides are needed. In general, isolation from natural sources and chemical synthesis are not cost‐effective. The relatively low cost and easy scale‐up of the recombinant approach renders it the most attractive means for large‐scale production of antimicrobial peptides. Among the many systems available for protein expression, Escherichia coli remains the most widely used host. Antimicrobial peptides produced in E. coli are often expressed as fusion proteins, which effectively masks these peptides' potential lethal effect towards the bacterial host and protects the peptides from proteolytic degradation. Although some carriers confer peptide solubility, others promote the formation of inclusion bodies. The present minireview considers the most commonly used carrier proteins for fusion expression of antimicrobial peptides in E. coli. The favourable properties of SUMO (small ubiquitin‐related modifier) as a novel fusion partner are also discussed.

Abstract
Peptide P(11)-4 (QQRFEWEFEQQ) was designed to self-assemble to form beta-sheets and nematic gels in the pH range 5-7 at concentrations > or =12.6 mM in water. This self-assembly is reversibly controlled by adjusting the pH of the solvent. It can also self-assemble into gels in biological media. This together with its biocompatibility and biodegradability make P(11)-4 an attractive building block for the fabrication of nanoscale materials with uses in, for example, tissue engineering. A limitation to large-scale production of such peptides is the high cost of solid phase chemical synthesis. We describe expression of peptide P(11)-4 in the bacterium Escherichia coli from constructs carrying tandem repeats of the peptide coding sequence. The vector pET31b+ was used to express P(11)-4 repeats fused to the ketosteroid isomerase protein which accumulates in easily recoverable inclusion bodies. Importantly, the use of auto-induction growth medium to enhance cell density and protein expression levels resulted in recovery of 2.5 g fusion protein/L culture in both shake flask and batch fermentation. Whole cell detergent lysis allowed recovery of inclusion bodies largely composed of the fusion protein. Cyanogen bromide cleavage followed by reverse phase HPLC allowed purification of the recombinant peptide with a C-terminal homoserine lactone (rP(11)-4(hsl)). This recombinant peptide formed pH dependent hydrogels, displayed beta-structure measured by circular dichroism and fibril formation observed by transmission electron microscopy.

Abstract
To produce large amounts of a peptide of fewer than 10 amino acid residues, construction of a gene encoding multimers of the small peptide is necessary. For this study a method was developed to facilitate the gene construction of high multimers of a small peptide with one step of cloning. A hypocholesterolemic peptide, IIAEK, from cow's milk beta-lactoglobulin was used as a model peptide for the construction of a gene encoding multimers of IIAEK and for the production of the peptide. Two systems for direct expression of 28-mers of IIAEK sequences (28IIAEK) and expression of 34 IIAEK sequences (4 IIAEK sequences in each of the disordered regions I, II, and III and 14 and 8 IIAEK sequences in disordered regions IV and V, respectively) in a mutant of soybean proglycinin A1aB1b lacking 31 residues in disordered region IV [A1aB1b(Delta31)-34IIAEK] were used. The protein produced from both systems formed inclusion bodies. The expression level of A1aB1b(Delta31)-34IIAEK was 29.9% of the total cell proteins and that of the 28IIAEK was 2.0%. The insoluble A1aB1b(Delta31)-34IIAEK was digested by trypsin without any help from urea or chemicals, and the produced IIAEK was purified using an octadecyl silica column. The yield of IIAEK was 58.6%. The results showed that A1aB1b as a carrier of multiple peptides and use of an Escherichia coli expression system are suitable for production of bioactive peptide.

Abstract
A method is presented that allows efficient production of antimicrobial peptides in bacteria by means of fusion to the histone fold domain of the human transcription factor TAF12. This small fusion partner drives high-level expression of peptides and leads to their accumulation in an entirely insoluble form, thereby eliminating toxicity to the host. Using the antimicrobial peptide LAH4 as an example, we demonstrate that neither affinity purification of the TAF12 fusion protein nor initial solubilization of inclusion bodies in denaturing buffers is required. Instead, crude insoluble material from bacteria is directly dissolved in formic acid for immediate release of the peptide through chemical cleavage at a unique Asp-Pro site. This is followed by purification to homogeneity in a single chromatographic step. Because of the elevated expression levels of the histone fold domain and its small size (8 kDa), this straightforward purification scheme produces yields in excess of 10 mg active peptide per liter of culture. We demonstrate that TAF12 fusion allows expression of a wide range of antimicrobial peptides as well as efficient isotope labeling for NMR studies.

Abstract
Antimicrobial peptides (AMPs) constitute an important component of the innate immune system in a variety of organisms. Buforin I is a 39-amino acid AMP that was first isolated from the stomach tissue of the Asian toad Bufo bufo gargarizans. Buforin II is a 21-amino acid peptide that is derived from buforin I and displays an even more potent antimicrobial activity than its parent AMP. Both peptides share complete sequence identity with the N-terminal region of histone H2A that interacts directly with nucleic acids. Buforin I is generated from histone H2A by pepsin-directed proteolysis in the cytoplasm of gastric gland cells. After secretion into the gastric lumen, buforin I remains adhered to the mucous biofilm that lines the stomach, thus providing a protective antimicrobial coat. Buforins, which house a helix-hinge-helix domain, kill a microorganism by entering the cell without membrane permeabilization and thus binding to nucleic acids. The proline hinge is crucial for the cell penetrating activity of buforins. Buforins also are known to possess anti-endotoxin and anticancer activities, thus making these peptides attractive reagents for pharmaceutical applications. This review describes the role of buforins in innate host defense; future research paradigms; and use of these agents as human therapeutics.

Abstract
We have produced a small antimicrobial peptide PFWRIRIRR in bacteria utilizing production in the form of insoluble fusion protein with ketosteroid isomerase. The recombinant peptide was rapidly and efficiently isolated by acidic cleavage of the fusion protein based on the acid labile Asp-Pro bond at the N-terminus of the peptide. The peptide has antibacterial activity and neutralizes macrophage activation by LPS. The selectivity of the peptide against bacteria correlates with preferential binding to acidic phospholipid vesicles. Solution structure of the peptide in SDS and DPC micelles was determined by NMR. The peptide adopts a well-defined structure, comprising a short helical segment. Cationic and hydrophobic clusters are segregated along the molecular axis of the short helix, which is positioned perpendicular to the membrane plane. The position of the helix is shifted in two micellar types and more nonpolar surface is exposed in anionic micelles. Overall structure explains the advantageous role of the N-terminal proline residue, which forms an integral part of the hydrophobic cluster.

Abstract
Arenicins are 21-residue cationic antimicrobial peptides isolated from marine polychaeta Arenicola marina. The peptides exhibit potent broad-spectrum antimicrobial activity. In water solution arenicin-2 adopts a beta-hairpin conformation, stabilized by one disulfide and nine hydrogen bonds. To determine the propensity for the peptide oligomerization in membrane mimetic systems, the recombinant arenicin-2 was overexpressed as a fused form in Escherichia coli. The arenicin-2 oligomerization and intermolecular packing in membrane mimicking environment were investigated using high-resolution NMR spectroscopy. The present studies show that arenicin-2 preserves a beta-hairpin structure and forms asymmetric dimers upon incorporation into the dodecylphosphocholine micelle. Two monomers of arenicin-2 are aligned parallel to each other by the N-terminal strands of the beta-hairpin (CN upward arrow upward arrowNC type of association). Polyacrylamide gel electrophoresis analysis indicated that in environment of anionic SDS micelles the arenicin-2 might undergo further oligomerization and form tetramers. Our results afford further molecular insight into possible mechanism of antimicrobial action of arenicins.

Abstract
The cysteine-rich peptide hepcidin is an antimicrobial peptide and iron transport regulator that has been found in vertebrates including birds, fish and mammals. To elucidate the structure and biological function of fish hepcidin, which is difficult to produce synthetically, we have cloned several plasmid constructs encoding hepcidin from Japanese flounder, Paralichthys olivaceus, and tested expression of recombinant peptides, each with an N-terminal hexahistidine (6xHis) tag, in inclusion bodies or the periplasmic space of Escherichia coli. Hepcidin expressed in inclusion bodies was reduced, and subsequently refolded using a dilution technique with a cysteine redox system. The oxidized His-hepcidin monomer was separated from protein multimers and mass spectrometry analysis showed that the peptide was of the predicted size and contained four disulfide bonds. Removal of the 6xHis tag was attempted using enzymatic cleavage by Factor Xa and tobacco etch virus (TEV) protease or chemical cleavage by hydroxylamine. The Factor Xa cleavage was unsuccessful and hydroxylamine cleavage resulted in aggregation of cleaved peptide. TEV protease cleavage was successful but immediately resulted in hexamer formation despite varying reaction conditions (redox, non-redox, pH, temperature, target protein concentration, type of buffer). However, the recombinant His-hepcidin fusion peptide monomer showed considerable antimicrobial activity. NMR-based studies showed that hepcidin contained a rare vicinal disulfide linkage at the top of a loop structure and a short beta-sheet structure encompassing residues 7-13 and 19-25 that is stabilized by three disulfide bonds.

Abstract
Apidaecins are heat-stable, nonhelical antibacterial peptides isolated from lymph fluid of the honeybee (Apis mellifera). These peptides are active against a wide range of gram-negative bacteria and they are the most prominent components of the honeybee humoral defense against microbial invasion. In the present study, one isoform of apidaecin, apidaecin Ho, was expressed extracellularly in the food-grade bacterium Lactococcus lactis. Results showed that expression driven by the lactococcal nisA promoter and Usp45 signal peptide resulted in efficient secretion of apidaecin in L. lactis subsp. cremoris NZ9000. Recombinant apidaecin was purified by gel filtration and semipreparative RP-HPLC, and about 10 mg active recombinant apidaecin was obtained from 1,000 ml culture. This is the first report on the nisin-controlled extracellular production of active apidaecin in L. lacits. The expression and delivery of apidaecin in the food-grade L. lactis may provide a clue to facilitate the widespread application of apidaecin in the control and prevention of gram-negative bacteria infections of human and animals.

Abstract
A novel strategy for constructing multiple joined genes of acidic partner-mediated antimicrobial peptide is described. This strategy allows the expression of antimicrobial peptide by Escherichia coli in a stable form and with high yield. Cecropin A (1-8)-melittin (1-10) (CAME) hybrid peptide was selected as a model of antimicrobial peptide. An acidic fragment from magainin intervening sequence was fused to the antimicrobial peptide as a partner to neutralize the lethal effects on the host cells. Multiple copies of the fusion peptide gene were tandemly linked and cloned into the expression vector pET21a. Multimers were expressed at high levels, reaching up to 36% of total cell proteins, and expression levels were proportional to the degree of multimerization. The fusion proteins were mainly expressed as inclusion bodies, probably owing to cysteine residues in the multimers. The target CAME peptide was obtained by cleaving the multimers with cyanogen bromide and purified by cation-exchange chromatography. Recombinant CAME peptide showed strong antimicrobial activities against both Gram-negative and -positive bacteria. These results might provide an efficient solution for high-level expression of various kinds of antimicrobial peptides that are toxic to the host.

Abstract
Direct expression of an antimicrobial peptide (AMP) in Escherichia coli causes several problems such as the toxicity of AMP to the host cell, its susceptibility to proteolytic degradation, and decreased antimicrobial activity due to the additional residue(s) introduced after cleavage of AMPs from fusion partners. To overcome these problems and produce a large quantity of a potent AMP histonin (RAGLQFPVGKLLKKLLKRLKR) in E. coli, an efficient expression system was developed, in which the toxicity of histonin was neutralized by a fusion partner F4 (a truncated fragment of PurF protein) and the productivity was increased by a multimeric expression of a histonin gene. The expression level of the fusion proteins reached a maximum with a 12-mer of a histonin gene. In addition, because of the RLKR residues present at the C terminus of histonin, furin cleavage of the multimeric histonin expressed produces an intact, natural histonin. The AMP activity of the histonin produced in E. coli was identical to that of a synthetic histonin. With our expression system, 167 mg of histonin was obtained from 1 l of E. coli culture. These results may lead to a cost-effective solution for the mass production of AMPs that are toxic to a host.

Abstract
The winter flounder (Pseudopleuronectes americanus) antimicrobial peptide pleurocidin was produced in Escherichia coli using a synthetic gene constructed by PCR. The gene expresses pleurocidin from pET21a fused to the C-terminus of an insoluble carrier peptide. Once expressed, the fusion peptide formed inclusion bodies in the cytoplasm that were collected, solubilized in guanidine-HCl, and chemically cleaved using hydroxylamine at a unique asparaginyl-glycyl dipeptide. This released recombinant pleurocidin (r-pleurocidin), which was purified using ultrafiltration followed by reverse phase chromatography. The r-pleurocidin peptide resolved as a single band (2.7 kDa) when analyzed by Tris-Tricine buffered SDS-PAGE, and its amino acid sequence was confirmed using tandem mass spectrometry. Extending the pleurocidin sequence with a C-terminal glycine (r-pleurocidin-G) suppressed production of the fusion peptide 15-fold. When pleurocidin was extended further to include aspartate (r-pleurocidin-GD), the same effect was observed, and when pleurocidin was extended with aspartate alone, no effect was observed. Expression of fusion peptide containing either r-pleurocidin-G or r-pleurocidin-GD with low concentrations of inductant caused E. coli to enter stationary phase prematurely, but did not affect overall growth rates. A partial production recovery of r-pleurocidin-G was achieved by inducing expression in stationary phase cells. We observed r-pleurocidin-G to have enhanced antimicrobial activity compared with r-pleurocidin, and we propose that this activity interferes with E. coli metabolism during expression. This antimicrobial effect is probably facilitated by residual solubility of the fusion peptide and by a C-terminal cap structure, which stabilizes the r-pleurocidin-G alpha-helix that is thought to be important for activity.

Abstract
Human beta-defensin-4 (hBD4) is a cationic 50-amino acid antimicrobial peptide with three conserved cysteine disulfide bonds. It exhibits a broad antimicrobial spectrum. This study describes the synthesis of hBD4 gene, the heterologous fusion expression of the peptide in Escherichia coli, and the bioactive assay of released hBD4. A PCR-based gene SOEing (splicing by overlap extension) synthesis method was used in the synthesis of the hBD4 gene with optimized codons. By constructing the expression plasmid (pET32-smhBD4), high concentration of soluble hBD4 fusion protein (1.9 g/l) can be obtained in E. coli. Further optimization studies showed that the expression system was very efficient to produce soluble target protein, and the solubility of the target protein could attain more than 99% even when the culture temperature was as high as 37 degrees C. The highest productivity (2.68 g/l) of the hBD4 fusion protein was achieved by cultivating the E. coli (pET32-smhBD4) in MBL medium at 34 degrees C, inducing the culture at the mid-exponential phase with 0.4-mM isopropyl beta-D-galactopyranoside (IPTG), and collecting the broth after 6-h expression. The soluble target protein accounted for 64.6% of the total soluble proteins, and the mature hBD4 expression level was stoichiometrically estimated to be 0.689 g/l. This fusion protein was then purified and cleaved to get the mature hBD4 peptide that showed antimicrobial activity against E. coli and Pseudomonas aeruginosa.

Abstract
Direct expression of lactoferricin, an antimicrobial peptide, is lethal to Escherichia coli. For the efficient production of lactoferricin in E. coli, we developed an expression system in which the gene for the lysine- and arginine-rich cationic lactoferricin was fused to an anionic peptide gene to neutralize the basic property of lactoferricin, and successfully overexpressed the concatemeric fusion gene in E. coli. The lactoferricin gene was linked to a modified magainin intervening sequence gene by a recombinational polymerase chain reaction, thus producing an acidic peptide-lactoferricin fusion gene. The monomeric acidic peptide-lactoferricin fusion gene was multimerized and expressed in E. coli BL21(DE3) upon induction with isopropyl-beta-D-thiogalactopyranoside. The expression levels of the fusion peptide reached the maximum at the tetramer, while further increases in the copy number of the fusion gene substantially reduced the peptide expression level. The fusion peptides were isolated and cleaved to generate the separate lactoferricin and acidic peptide. About 60 mg of pure recombinant lactoferricin was obtained from 1 L of E. coli culture. The purified recombinant lactoferricin was found to have a molecular weight similar to that of chemically synthesized lactoferricin. The recombinant lactoferricin showed antimicrobial activity and disrupted bacterial membrane permeability, as the native lactoferricin peptide does.

[PMID: 16249097 DOI: 10.1016/j.pep.2005.08.023] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2005] [Revised: 08/25/2005] [Accepted: 08/26/2005] [Indexed: 10/25/2022]
Abstract
Self-assembling peptides have emerged as an attractive scaffold material for tissue engineering, yet the expense associated with solid phase chemical synthesis has limited their broad use. In addition, the fidelity of chemical synthesis constrains the length of polypeptides that can be produced homogeneously by this method. Template-derived biosynthesis by recombinant DNA technology may overcome both of these problems. However, recovery of polypeptides from recombinant protein expression systems typically involves multi-step purification schemes. In this study, we report an integrated approach to recombinantly produce and purify self-assembling peptides from the recently developed expression host Ralstonia eutropha. The purification is based on the specific affinity of carbohydrate binding modules (CBMs) to cellulose. In a first step, we identified CBMs that express well in R. eutropha by assembling a fusion library of green fluorescent protein (GFP) and CBMs and determining the fluorescence of cell-free extracts. Three GFP::CBM fusions were found to express at levels similar to GFP alone, of which two CBMs were able to mediate cellulose binding of the GFP::CBM fusion. These two CBMs were then fused to multiple repeats of the self-assembling peptide RAD16-I::E (N-RADARADARADARADAE-C). The fusion protein CBM::E::(RAD16-I::E)4 was expressed in R. eutropha and purified using the CBM's affinity for cellulose. Subsequent proteolytic cleavage with endoproteinase GluC liberated RAD16-I::E peptide monomers with similar properties to the chemically synthesized counterpart RAD16-I.

Abstract
Antimicrobial peptides are part of the innate immune system of vertebrates and invertebrates. They are active against gram-negative and gram-positive bacteria, fungi, and protozoa. Currently, most antimicrobial peptides are extracted from host organisms or produced by solid-phase peptide synthesis. Recombinant protein expression in Escherichia coli is a tool for greater production yields at a decreased cost and reduces the use of hazardous materials. We have constructed a concatamer of indolicidin and successfully expressed a fusion product with thioredoxin in E. coli BL21DE3. Codons for methionine residues flanking individual indolicidin genes were incorporated for cyanogen bromide cleavage of the fusion protein and liberation of active monomeric indolicidin. Peptide yields of 150 microg/l monomeric indolicidin were achieved in this first report of recombinant production of indolicidin with demonstrated antimicrobial activity.

Abstract
Adenoregulin is a 33 amino acid antimicrobial peptide isolated from the skin of the arboreal frog Phyllomedusa bicolor. Natural adenoregulin is synthesized with an amidated valine residue at C-terminus and shows lethal effects against filamentous fungi, as well as a broad spectrum of pathogenic microorganisms. A synthetic gene for adenoregulin (ADR) with an additional amino acid glutamine at C-terminus was cloned into pET32a vector to allow expression of ADR as a Trx fusion protein in Escherichia coli BL21(DE3). The resulting expression level of the fusion protein could reach up to 20% of the total cell proteins. The fusion protein could be purified effectively by Ni2+-chelating chromatography. Released from the fusion protein by enterokinase cleavage and purified to homogeneity, the recombinant ADR displayed antimicrobial activity similar to that of the synthetic ADR reported earlier. Comparing the antimicrobial activities of the recombinant adenoregulin with C-amidated terminus to that without an amidated C-terminus, we found that the amide of glutamine at C-terminus of ADR improved its potency on certain microorganisms such as Tritirachium album and Saccharomyces cerevisiae.
