Abstract
There is an urgent need for influenza vaccines that offer broad cross-protection. The highly conserved ectodomain of the influenza matrix protein 2 (M2e) is a promising candidate; however, its low immunogenicity can be addressed. In this study, we developed influenza vaccines using the Lumazine synthase (LS) platform. The primary objective of this study was to determine the protective potential of M2e proteins expressed on Lumazine synthase (LS) nanoparticles. M2e-LS proteins, produced through the E. coli system, spontaneously assemble into nanoparticles. The study investigated the efficacy of the M2e-LS nanoparticle vaccine in mice. Mice immunized with M2e-LS nanoparticles exhibited significantly higher levels of intracellular cytokines than those receiving soluble M2e proteins. The M2e-LS protein exhibited robust immunogenicity and provided 100% protection against cross-clade influenza.

Expression of BSN314 lysozyme genes in Escherichia coli BL21: a study to demonstrate microbicidal and disintegarting potential of the cloned lysozyme. Braz J Microbiol 2024; 55:215-233. [PMID: 38146050 PMCID: PMC10920529 DOI: 10.1007/s42770-023-01219-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2023] [Accepted: 12/14/2023] [Indexed: 12/27/2023] Open
Abstract
This study is an extension of our previous studies in which the lysozyme was isolated and purified from Bacillus subtilis BSN314 (Naveed et al., 2022; Naveed et al., 2023). In this study, the lysozyme genes were cloned into the E. coli BL21. For the expression of lysozyme in E. coli BL21, two target genes, Lyz-1 and Lyz-2, were ligated into the modified vector pET28a to generate pET28a-Lyz1 and pET28a-Lyz2, respectively. To increase the production rate of the enzyme, 0.5-mM concentration of IPTG was added to the culture media and incubated at 37 °C and 220 rpm for 24 h. Lyz1 was identified as N-acetylmuramoyl-L-alanine amidase and Lyz2 as D-alanyl-D-alanine carboxypeptidase. They were purified by multi-step methodology (ammonium sulfate, precipitation, dialysis, and ultrafiltration), and antimicrobial activity was determined. For Lyz1, the lowest MIC/MBC (0.25 μg/mL; with highest ZOI = 22 mm) were recorded against Micrococcus luteus, whereas the highest MIC/MBC with lowest ZOI were measured against Salmonella typhimurium (2.50 μg /mL; with ZOI = 10 mm). As compared with Aspergillus oryzae (MIC/MFC; 3.00 μg/mL), a higher concentration of lysozyme was required to control the growth of Saccharomyces cerevisiae (MIC/MFC; 50 μg/mL). Atomic force microscopy (AFM) was used to analyze the disintegrating effect of Lyz1 on the cells of selected Gram-positive bacteria, Gram-negative bacteria, and yeast. The AFM results showed that, as compared to Gram-negative bacteria, a lower concentration of lysozyme (Lyz1) was required to disintegrate the cell of Gram-positive bacteria.

Abstract
Ganoderma capense is a precious medicinal fungus in China. In this study, a novel fungal immunomodulatory protein gene, named as FIP-gca, was cloned from G. capense by homologous cloning. Sequencing analysis indicated that FIP-gca was composed of 336 bp, which encoded a polypeptide of 110 amino acids. Protein sequence blasting and phylogenetic analysis showed that FIP-gca shared homology with other Ganoderma FIPs. FIP-gca was effectively expressed in Pichia pastoris GS115 at an expression level of 166.8 mg/L and purified using HisTrap™ fast-flow prepack columns. The immunomodulation capacity of rFIP-gca was demonstrated by that rFIP-gca could obviously stimulate cell proliferation and increase IL-2 secretion of murine spleen lymphocytes. Besides, antitumor activity of rFIP-gca towards human stomach cancer AGS cell line was evaluated in vitro. Cell wound scratch assay proved that rFIP-gca could inhibit migration of AGS cells. And flow cytometry assay revealed that rFIP-gca could significantly induce apoptosis of AGS cells. rFIP-gca was able to induce 18.12% and 22.29% cell apoptosis at 0.3 μM and 0.6 μM, respectively. Conclusively, the novel FIP-gca gene from G. capense has been functionally expressed in Pichia and rFIP-gca exhibited ideal immunomodulation and anti-tumour activities, which implies its potential application and study in future.

Molecules 2023; 28:molecules28031058. [PMID: 36770725 PMCID: PMC9919333 DOI: 10.3390/molecules28031058] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/12/2023] [Accepted: 01/17/2023] [Indexed: 01/21/2023] Open
Abstract
In the present study, lysozyme was purified by the following multi-step methodology: salt (ammonium sulfate) precipitation, dialysis, and ultrafiltration. The lysozyme potential was measured by enzymatic activity after each purification step. However, after ultrafiltration, the resulting material was considered extra purified. It was concentrated in an ultrafiltration centrifuge tube, and the resulting protein/lysozyme was used to determine its bactericidal potential against five bacterial strains, including three gram-positive (Bacillus subtilis 168, Micrococcus luteus, and Bacillus cereus) and two gram-negative (Salmonella typhimurium and Pseudomonas aeruginosa) strains. The results of ZOI and MIC/MBC showed that lysozyme had a higher antimicrobial activity against gram-positive than gram-negative bacterial strains. The results of the antibacterial activity of lysozyme were compared with those of ciprofloxacin (antibiotic). For this purpose, two indices were applied in the present study: antimicrobial index (AMI) and percent activity index (PAI). It was found that the purified lysozyme had a higher antibacterial activity against Bacillus cereus (AMI/PAI; 1.01/101) and Bacillus subtilis 168 (AMI/PAI; 1.03/103), compared to the antibiotic (ciprofloxacin) used in this study. Atomic force microscopy (AFM) was used to determine the bactericidal action of the lysozyme on the bacterial cell. The purified protein was further processed by gel column chromatography and the eluate was collected, its enzymatic activity was 21.93 U/mL, while the eluate was processed by native-PAGE. By this analysis, the un-denatured protein with enzymatic activity of 40.9 U/mL was obtained. This step shows that the protein (lysozyme) has an even higher enzymatic potential. To determine the specific peptides (in lysozyme) that may cause the bactericidal potential and cell lytic/enzymatic activity, the isolated protein (lysozyme) was further processed by the SDS-PAGE technique. SDS-PAGE analysis revealed different bands with sizes of 34 kDa, 24 kDa, and 10 kDa, respectively. To determine the chemical composition of the peptides, the bands (from SDS-PAGE) were cut, enzymatically digested, desalted, and analyzed by LC-MS (liquid chromatography-mass spectrometry). LC-MS analysis showed that the purified lysozyme had the following composition: the number of proteins in the sample was 56, the number of peptides was 124, and the number of PSMs (peptide spectrum matches) was 309. Among them, two peptides related to lysozyme and bactericidal activities were identified as: A0A1Q9G213 (N-acetylmuramoyl-L-alanine amidase) and A0A1Q9FRD3 (D-alanyl-D-alanine carboxypeptidase). The corresponding protein sequence and nucleic acid sequence were determined by comparison with the database.

Appl Microbiol Biotechnol 2021; 105:2799-2813. [PMID: 33763709 DOI: 10.1007/s00253-021-11225-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 02/24/2021] [Accepted: 03/07/2021] [Indexed: 10/21/2022]
Abstract
Fungal immunomodulatory proteins (FIPs) are bioactive proteins with immunomodulatory properties. We previously reported the heterologous production in Escherichia coli of FIP-Lrh from Tiger milk mushroom (Lignosus rhinocerus) with potent cytotoxic effect on cancer cell lines. However, protein produced in E. coli lacks post-translational modifications and may be contaminated with lipopolysaccharide (LPS) endotoxin. Therefore, in this study, yFIP-Lrh produced in Pichia pastoris was functionally compared with eFIP-Lrh produced in E. coli. Expression construct of FIP-Lrh cDNA in pPICZα was generated, transformed into P. pastoris X-33 and Mut+ transformants were verified by colony PCR. Induction with 0.5% or 1% methanol resulted in a secreted 13.6 kDa yFIP-Lrh which was subsequently purified and verified using LCMS/MS analysis. Size exclusion chromatography confirmed eFIP-Lrh as a homodimer whereas the larger size of yFIP-Lrh may indicate post-translational modification despite negative for glycoproteins staining. At lower concentration (4-8 μg/mL), yFIP-Lrh induced significantly higher Th1 (IFN-γ, TNF-α) and Th2 (IL-6, IL-4, IL-5, IL-13) cytokines production in mice splenocytes, whereas 16 μg/mL eFIP-Lrh induced significantly higher pro-inflammatory cytokines (TNF-α, IL-6, IL-10), possibly due to higher residual LPS endotoxin (0.082 EU/mL) in eFIP-Lrh compared to negligible level in yFIP-Lrh (0.001 EU/mL). Furthermore, yFIP-Lrh showed higher cytotoxic effect on MCF-7 and HeLa cancer cells. Since both recombinant proteins of FIP-Lrh have the same peptide sequence, besides glycosylation, other post-translational modifications in yFIP-Lrh may account for its enhanced immunomodulatory and anti-proliferative activities. In conclusion, P. pastoris is preferred over E. coli for production of a functionally active yFIP-Lrh devoid of endotoxin contamination. KEY POINTS: • FIP-Lrh can induced production of Th1 and Th2 cytokines by mouse splenocytes. • Higher cytotoxic effect on cancer cells observed for yeast compared to E. coli produced FIP-Lrh. • P. pastoris allows production of an endotoxin-free and functionally active recombinant FIP-Lrh.

Abstract
Fungal immunomodulatory proteins (FIPs) are fascinating small and heat-stable bioactive proteins in a distinct protein family due to similarities in their structures and sequences. They are found in fungi, including the fruiting bodies producing fungi comprised of culinary and medicinal mushrooms. Structurally, most FIPs exist as homodimers; each subunit consisting of an N-terminal α-helix dimerization and a C-terminal fibronectin III domain. Increasing numbers of identified FIPs from either different or same fungal species clearly indicates the growing research interests into its medicinal properties which include immunomodulatory, anti-inflammation, anti-allergy, and anticancer. Most FIPs increased IFN-γ production in peripheral blood mononuclear cells, potentially exerting immunomodulatory and anti-inflammatory effects by inhibiting overproduction of T helper-2 (Th2) cytokines common in an allergy reaction. Recently, FIP from Ganoderma microsporum (FIP-gmi) was shown to promote neurite outgrowth for potential therapeutic applications in neuro-disorders. This review discussed FIPs' structural and protein characteristics, their recombinant protein production for functional studies, and the recent advances in their development and applications as pharmaceutics and functional foods.

Abstract
In order to obtain a better fermentation parameter for the production of recombinant Ganoderma lucidum immunomodulatory protein (rFIP-glu), an engineered Pichia pastoris GS115 was investigated on the fermentation time, temperature, methanol concentration and initial pH of media, while immunomodulatory activities of the rFIP-glu was confirmed. L9(33) orthogonal experiment were firstly employed to optimize various fermentation parameters in the shake-flask level. The optimized fermentation parameters were subsequently verified in a 5 L fermenter. Biological activities including cell viability and tumor necrosis factor-alpha (TNF-α) mRNA of the rFIP-glu were evaluated on murine macrophage RAW264.7 cells. The results showed that the yield of rFIP-glu was up to 368.71 μg/ml in the shake-flask, and 613.47 μg/ml in the 5 L fermenter, when the Pichia pastoris was incubated in basic media with the methanol concentration 1.0% and initial pH 6.5, and with constant shaking at 280 rpm for 4 days at 26 °C. In vitro assays of biological activity indicated that rFIP-glu had significant toxicity against RAW264.7 cells, and possessed the ability to induce TNF-α mRNA expression in macrophage RAW264.7 cells. In conclusion, engineered P. pastoris showed a good fermentation property under the optimum fermentation parameters. It could be a candidate industrial strain for further study.

Recombinant Expression and Bioactivity Comparison of Four Typical Fungal Immunomodulatory Proteins from Three Main Ganoderma Species. BMC Biotechnol 2018; 18:80. [PMID: 30547780 PMCID: PMC6295072 DOI: 10.1186/s12896-018-0488-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2018] [Accepted: 11/28/2018] [Indexed: 02/09/2023] Open
Abstract
Background More than a dozen of fungal immunomodulatory proteins (FIPs) have been identified to date, most of which are from Ganoderma species. However, little is known about the similarities and differences between different Ganoderma FIPs’ bioactivities. In the current study, two FIP genes termed FIP-gap1 and FIP-gap2 from G. applanatum, along with LZ-8 and FIP-gsi, another two representative Ganoderma FIP genes from G. lucidum and G. sinense were functionally expressed in Pichia. Subsequently, bioactivities of four recombinant Ganoderma FIPs were demonstrated and compared. Results All the four Ganoderma FIP genes could be effectively expressed in P. pastoris GS115 at expression levels ranging from 197.5 to 264.3 mg L− 1 and simply purified by one step chromatography using HisTrap™ FF prepack columns. Amino acid sequence analysis showed that they all possessed the FIP conserved fragments. The homologies of different Ganoderma FIPs were from 72.6 to 86.4%. In vitro haemagglutination exhibited that FIP-gap1, FIP-gsi and LZ-8 could agglutinate human, sheep and mouse red blood cells but FIP-gap2 agglutinated none. Besides, the immunomodulation activities of these Ganoderma FIPs were as: rFIP-gap2 > rFIP-gap1 > rLZ-8 and rFIP-gsi in terms of proliferation stimulation and cytokine induction on murine splenocytes. Additionally, the cytotoxic activity of different FIPs was: rFIP-gap1 > rLZ-8 > rFIP-gsi > rFIP-gap2, examined by their inhibition of three human carcinomas A549, Hela and MCF-7. Conclusions Taken together, four typical Ganoderma FIP genes could be functionally expressed in P. pastoris, which might supply as feasible efficient resources for further study and application. Both similarities and differences were indeed observed between Ganoderma FIPs in their amino acid sequences and bioactivities. Comprehensively, rFIP-gaps from G. applanatum proved to be more effective in immunomodulation and cytotoxic assays in vitro than rLZ-8 (G. lucidum) and rFIP-gsi (G. sinense).

Abstract
The success of gene and cell therapy in clinic during the past two decades as well as our expanding ability to manipulate these biomaterials are leading to new therapeutic options for a wide range of inherited and acquired diseases. Combining conventional therapies with this emerging field is a promising strategy to treat those previously-thought untreatable diseases. Traditional Chinese medicine (TCM) has evolved for thousands of years in China and still plays an important role in human health. As part of the active ingredients of TCM, proteins and peptides have attracted long-term enthusiasm of researchers. More recently, they have been utilized in gene and cell therapy, resulting in promising novel strategies to treat both cancer and non-cancer diseases. This manuscript presents a critical review on this field, accompanied with perspectives on the challenges and new directions for future research in this emerging frontier.

Abstract
Human interferon-gamma (hIFNG) production is limited by various gene-level bottlenecks including translation, protein folding, and secretion which depends upon the physiological state of the organism. In this study gene-level and substrate-level modulations have been used to control Bacillus subtilis physiology for >15 fold extracellular soluble hIFNG production. Two variants of the native human interferon-gamma gene (hifng) were designed and synthesized, namely, cohifnghis and cohifng having codon adaptation index 25.33 and 26.89% higher than the native gene, respectively. BScoIFNG and BScoIFNGhis with ΔG of -100.0 and -113.7 kcal mol-1 resulted in 30 and 6.5% higher hIFNG compared to the native gene in complex medium. BScoIFNG produced 1.53 fold higher hIFNG using glucose-based defined medium as compared to the complex medium by modulating the physiological parameter growth rate from 0.35 to 0.26 hr-1. Further modulatory effect of various phosphotransferase transport system (PTS) and no-PTS sugars, sugar alcohols, and organic acids was quantified on the physiology of B. subtilis WB800N for extracellular hIFNG production. Sorbitol and glycerol emerged as the best hIFNG producers with lowest growth and substrate consumption rates. BScoIFNG produced maximum 3.15 mg L-1 hIFNG at 50 g L-1 glycerol with highest hIFNG yield (Yp/x = 0.136) and lowest substrate uptake rate (qs = 0.26).

Abstract
Characterization of PTS-IIC, an endogenous constitutive promoter from L. lactis.. Cellobiose enhances activity from PTS-IIC promoter. PTS-IIC promoter mediates protein expression in B. subtilis and E coli Nissle 1917.
Constitutively active promoter elements for heterologous protein production in Lactococcus lactis are scarce. Here, the promoter of the PTS-IIC gene cluster from L. lactis NZ3900 is described. This promoter was cloned upstream of an enhanced green fluorescent protein, GFPmut3a, and transformed into L. lactis. Transformants produced up to 13.5 μg of GFPmut3a per milliliter of log phase cells. Addition of cellobiose further increased the production of GFPmut3a by up to two-fold when compared to glucose. Analysis of mutations at two specific positions in the PTS-IIC promoter showed that a ‘T’ to ‘G’ mutation within the −35 element resulted in constitutive expression in glucose, while a ‘C’ at nucleotide 7 in the putative cre site enhanced promoter activity in cellobiose. Finally, this PTS-IIC promoter is capable of mediating protein expression in Bacillus subtilis and Escherichia coli Nissle 1917, suggesting the potential for future biotechnological applications of this element and its derivatives.

Abstract
The intein expression system has been widely applied in Escherichia coli to express various proteins and peptides. However, the removal of endotoxin from the recombinant proteins expressed in E. coli is very difficult and therefore complicates the purification process. In this study, we constructed an intein-based expression vector for an antimicrobial peptide (cathelicidin from Bungarus fasciatus) and expressed the intein fusion peptide in a Bacillus subtilis expression system. The fusion peptide was secreted into the culture medium, identified by Western blot and purified by affinity chromatography and intein self-cleavage in just one step. Approximately, 0.5 mg peptide was obtained from 1 litre of culture medium. The purified peptide showed antimicrobial activity. Our results indicate that the intein expression system may be a safe and efficient method to produce soluble peptides and proteins in B. subtilis.

Abstract
Small ubiquitin-related modifier (SUMO) technology has been widely used in Escherichia coli expression systems to produce antimicrobial peptides. However, E. coli is a pathogenic bacterium that produces endotoxins and can secrete proteins into the periplasm, forming inclusion bodies. In our work, cathelicidin-BF (CBF), an antimicrobial peptide purified from Bungarus fasciatus venom, was produced in a Bacillus subtilis expression system using SUMO technology. The chimeric genes his-SUMO-CBF and his-SUMO protease 1 were ligated into vector pHT43 and expressed in B. subtilis WB800N. Approximately 22 mg of recombinant fusion protein SUMO-CBF and 1 mg of SUMO protease 1 were purified per liter of culture supernatant. Purified SUMO protease 1 was highly active and cleaved his-SUMO-CBF with an enzyme-to-substrate ratio of 1:40. Following cleavage, recombinant CBF was further purified by affinity and cation exchange chromatography. Peptide yields of ~3 mg/l endotoxin-free CBF were achieved, and the peptide demonstrated antimicrobial activity. This is the first report of the production of an endotoxin-free antimicrobial peptide, CBF, by recombinant DNA technology, as well as the first time purified SUMO protease 1 with high activity has been produced from B. subtilis. This work has expanded the application of SUMO fusion technology and may represent a safe and efficient way to generate peptides and proteins in B. subtilis.

Abstract
Background Protein folding in the envelope is a crucial limiting step of protein export and secretion. In order to better understand this process in Lactococcus lactis, a lactic acid bacterium, genes encoding putative exported folding factors like Peptidyl Prolyl Isomerases (PPIases) were searched for in lactococcal genomes. Results In L. lactis, a new putative membrane PPIase of the cyclophilin subfamily, PpiA, was identified and characterized. ppiA gene was found to be constitutively expressed under normal and stress (heat shock, H2O2) conditions. Under normal conditions, PpiA protein was synthesized and released from intact cells by an exogenously added protease, showing that it was exposed at the cell surface. No obvious phenotype could be associated to a ppiA mutant strain under several laboratory conditions including stress conditions, except a very low sensitivity to H2O2. Induction of a ppiA copy provided in trans had no effect i) on the thermosensitivity of an mutant strain deficient for the lactococcal surface protease HtrA and ii) on the secretion and stability on four exported proteins (a highly degraded hybrid protein and three heterologous secreted proteins) in an otherwise wild-type strain background. However, a recombinant soluble form of PpiA that had been produced and secreted in L. lactis and purified from a culture supernatant displayed both PPIase and chaperone activities. Conclusions Although L. lactis PpiA, a protein produced and exposed at the cell surface under normal conditions, displayed a very moderate role in vivo, it was found, as a recombinant soluble form, to be endowed with folding activities in vitro.

Abstract
In the 1990s, significant efforts were invested in the research and development of food-grade expression systems in lactic acid bacteria (LAB). At this time, Lactococcus lactis in particular was demonstrated to be an ideal cell factory for the food-grade production of recombinant proteins. Steady progress has since been made in research on LAB, including Lactococcus, Lactobacillus and Streptococcus, in the areas of recombinant enzyme production, industrial food fermentation, and gene and metabolic pathway regulation. Over the past decade, this work has also led to new approaches on chromosomal integration vectors and host/vector systems. These newly constructed food-grade gene expression systems were designed with specific attention to self-cloning strategies, food-grade selection markers, plasmid replication and chromosomal gene replacements. In this review, we discuss some well-characterized chromosomal integration and food-grade host/vector systems used in LAB, with a special focus on sustainability, stability and overall safety, and give some attractive examples of protein expression that are based on these systems.

Abstract
DNA vaccine has been suggested to use in cancer therapy, but the efficacy remains to be improved. The immunostimulatory effect of a fungal immunomodulatory protein Ling Zhi-8 (LZ-8) isolated from Ganoderma lucidum has been reported. In this study, we tested the adjuvanticity of LZ-8 for HER-2/neu DNA vaccine against p185(neu) expressing tumor MBT-2 in mice. We found that recombinant LZ-8 stimulated mouse bone marrow-derived dendritic cells (DCs) via TLR4 and its stimulatory effect was not due to any microbe contaminant. In addition, LZ-8 enhanced the ability of DCs to induce antigen-specific T cell activation in vitro and in a subunit vaccine model in vivo. Surprisingly, LZ-8 cotreatment strongly improved the therapeutic effect of DNA vaccine against MBT-2 tumor in mice. This increase in antitumor activity was attributed to the enhancement of vaccine-induced Th1 and CTL responses. Consistent with the results from DCs, the promoting effect of LZ-8 on DNA vaccine was diminished when the MBT-2 tumor cells were grown in TLR4 mutant mice. Thus, we concluded that LZ-8 may be a promising adjuvant to enhance the efficacy of DNA vaccine by activating DCs via TLR4.

Abstract
With the exception of polysaccharides and triterpenes/triterpenoids compounds, fungal immunomodulatory protein (FIP), a small molecule protein, is also an important bioactive component with immune regulating activity. It plays a significant role in immunomodulating. The objective of this paper was to review the latest advances in various aspects of research on FIPs, including their basic components and structural character, characters of diversity, gene cloning and expression, and their biological function, etc. In addition, prospects of utilization value and the exploitation foreground of FIPs were also discussed.

FMB-1 in Lactococcus lactis MG1363. BIORESOURCE TECHNOLOGY 2010; 101:8828-8833. [PMID: 20620050 DOI: 10.1016/j.biortech.2010.06.068] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/11/2010] [Revised: 06/07/2010] [Accepted: 06/11/2010] [Indexed: 05/29/2023]
Abstract
Sucrose isomerase (SIase) has been used to produce palatinose, a structural isomer of sucrose, which has many beneficial health properties, such as low-glycemic and low-insulinemic indices. A gene corresponding to SIase from Enterobacter sp. FMB-1 was expressed in Lactococcus lactis MG1363 using the P170 expression system. The autoinducible promoter (P170) and an optimized signal peptide (SP310mut2) were used to induce and secrete SIase in L. lactis. One-step Ni-NTA affinity chromatography and Western blot analysis demonstrated that SIase was successfully secreted to the culture supernatant, although 60% of the recombinant enzymes were retained inside the cells. The production of the recombinant SIase was highly correlated with pH (pH 6) and glucose concentration (30g/L) of the medium. The extracellularly produced recombinant SIase was functionally active, effectively transforming 50g/L sucrose to 36g/L palatinose, with a conversion rate of 72% in the culture supernatant.

Abstract
Bioactive components in Ganoderma lucidum mainly include polysaccharides (PS-G) and immunomodulatory protein Ling Zhi-8 (LZ-8). These components may have diverse regulatory functions in the immune system. However, the PS-G preparations from different procedures still contained partial LZ-8 residue, indicating that the specific target and regulating function of PS-G and LZ-8 were not fully understood. In the present study, PS-G was subjected to 15% TCA for removing proteins and the LZ-8 detection using anti-LZ-8 monoclonal antibodies showed a remarkable 89.7% protein reduction of the deproteinized PS-G (dpPS-G). The Saccharomyces cerevisiae which expressed recombinant LZ-8 protein (rLZ-8) without glycosylation was generated and then compared with dpPS-G in the induction toward murine primary macrophage and T lymphocytic cells. The peritoneal macrophages from TLR4-deficient and wild type mice revealed that TLR4 was a putative receptor of dpPS-G, mediating the TNF-alpha, IL-1beta and IL-12p70 cytokine production and CD86, MHC II expression on macrophages, while rLZ-8 enhanced the production of IL-1beta, IL-12p70, CD86, and MHC II expression by another obscure route. rLZ-8-treated macrophages enhanced the release of IFN-gamma and IL-2 by murine CD4(+) and CD8(+) T cells, whereas dpPS-G treatment did not enhance the release of IFN-gamma and IL-2. Furthermore, although the direct rLZ-8-treatment conduced dramatic CD154, CD44 expression on CD3(+) T cells and increased IL-2, IFN-gamma secretion on CD4(+) and CD8(+) T cells, the dpPS-G was incapable of priming CD3(+), CD4(+) or CD8(+) T cells unitarily. Taken together, these results demonstrated that LZ-8 could activate murine macrophages and T lymphocytes but PS-G was merely the activator for macrophages, suggesting their diverse roles in activating the innate and adaptive immunity.

Abstract
Ganoderma sinensis fungal immunomodulatory protein (FIP-gsi) was a new member of FIPs family. Based on the cloning of FIP-gsi gene from G. sinensis, this paper reported that FIP-gsi gene was expressed in Escherichia coli expression system. Then, the recombinant proteins were analyzed by the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). Finally, the immunomodulatory activity was examined by inducing cytokine genes expression. The results showed that the recombinant FIP-gsi protein could be expressed in E. coli and got the yield of about 25% of the soluble form in the total soluble protein. The FIP-gsi protein was composed of 111 amino acids, and the sequence of homologous rate was 88.6% with FIP-glu (LZ-8). Furthermore, it could enhance the levels of interleukin (IL)-2, IL-3, IL-4, interferon gamma, tumor necrosis factor alpha, and IL-2 receptor (IL-2R) in mouse spleen cells.

Abstract
In this study, a novel recombinant type I antifreeze protein analogue (rAFP) was produced and secreted by Lactococcus lactis, a food-grade microorganism of major commercial importance. Antifreeze proteins are potent cryogenic protection agents for the cryopreservation of food and pharmaceutical materials. A food-grade expression and fermentation system (BSE- and antibiotic-free) for the production and secretion of high levels of rAFP was developed. Lyophilized, crude rAFP produced by L. lactis was tested in a frozen meat and frozen dough processing model. The frozen meat treated with the antifreeze protein showed less drip loss, less protein loss, and a high score on juiciness by sensory evaluation. Frozen dough treated with the rAFP showed better fermentation capacity than untreated frozen dough. Breads baked from frozen dough treated with rAFP acquired the same consumer acceptance as fresh bread.

Abstract
Lactococcus lactis is a food-grade microorganism of major commercial importance. Antifreeze protein is a potent cryogenic protection agent for the cryopreservation of food and pharmaceutical materials. In this study, extracellular expression of a novel recombinant type I antifreeze protein analogue (rAFP) in L. lactis was optimized. An efficient SlpA promoter (P SlpA) was fused to various signal peptides (SPs) and propeptide sequences to examine the extracellular expression levels of rAFP. An efficient signal peptide, SP sacB, fused to prosequence AE, enabled higher extracellular rAFP production; use of the SlpA terminator (Ter SlpA) was a further improvement. The extracellularly expressed rAFP successfully inhibited ice recrystallization and is thus potentially applicable for cryogenic preservation.
