Abstract
Hyaluronidases catalyze the degradation of hyaluronan (HA), which is finding rising applications in medicine, cosmetic, and food industries. Recombinant expression of hyaluronidases in microbial hosts has been given special attention as a sustainable way to substitute animal tissue-derived hyaluronidases. In this study, we focused on optimizing the secretion of hyaluronidase from Homo sapiens in Pichia pastoris by secretion pathway engineering. The recombinant hyaluronidase was first expressed under the control of a constitutive promoter PGCW14. Then, two endoplasmic reticulum-related secretory pathways were engineered to improve the secretion capability of the recombinant strain. Signal peptide optimization suggested redirecting the protein into co-translational translocation using the ost1-proα signal sequence improved the secretion level by 20%. Enhancing the co-translational translocation by overexpressing signal recognition particle components further enhanced the secretory capability by 48%. Then, activating the unfolded protein response by overexpressing a transcriptional factor ScHac1p led to a secreted hyaluronidase activity of 4.06 U/mL, which was 2.1-fold higher than the original strain. Finally, fed-batch fermentation elevated the production to 19.82 U/mL. The combined engineering strategy described here could be applied to enhance the secretion capability of other proteins in yeast hosts. KEY POINTS: • Improving protein secretion by enhancing co-translational translocation in P. pastoris was reported for the first time. • Overexpressing Hac1p homologous from different origins improved the rhPH-20 secretion. • A 4.9-fold increase in rhPH-20 secretion was achieved after fermentation optimization and fed-batch fermentation.

Komagataella phaffii as a Platform for Heterologous Expression of Enzymes Used for Industry. Microorganisms 2024; 12:346. [PMID: 38399750 PMCID: PMC10892927 DOI: 10.3390/microorganisms12020346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/01/2024] [Accepted: 02/03/2024] [Indexed: 02/25/2024] Open
Abstract
In the 1980s, Escherichia coli was the preferred host for heterologous protein expression owing to its capacity for rapid growth in complex media; well-studied genetics; rapid and direct transformation with foreign DNA; and easily scalable fermentation. Despite the relative ease of use of E. coli for achieving the high expression of many recombinant proteins, for some proteins, e.g., membrane proteins or proteins of eukaryotic origin, this approach can be rather ineffective. Another microorganism long-used and popular as an expression system is baker's yeast, Saccharomyces cerevisiae. In spite of a number of obvious advantages of these yeasts as host cells, there are some limitations on their use as expression systems, for example, inefficient secretion, misfolding, hyperglycosylation, and aberrant proteolytic processing of proteins. Over the past decade, nontraditional yeast species have been adapted to the role of alternative hosts for the production of recombinant proteins, e.g., Komagataella phaffii, Yarrowia lipolytica, and Schizosaccharomyces pombe. These yeast species' several physiological characteristics (that are different from those of S. cerevisiae), such as faster growth on cheap carbon sources and higher secretion capacity, make them practical alternative hosts for biotechnological purposes. Currently, the K. phaffii-based expression system is one of the most popular for the production of heterologous proteins. Along with the low secretion of endogenous proteins, K. phaffii efficiently produces and secretes heterologous proteins in high yields, thereby reducing the cost of purifying the latter. This review will discuss practical approaches and technological solutions for the efficient expression of recombinant proteins in K. phaffii, mainly based on the example of enzymes used for the feed industry.

Biodegradation 2023; 34:549-566. [PMID: 37354270 DOI: 10.1007/s10532-023-10041-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 05/30/2023] [Indexed: 06/26/2023]
Abstract
The present study aimed to screen and optimize lipase production by the Antarctic strain Acinetobacter johnsonii Ant12 for lipid-rich wastewater treatment. Lipase production was successfully enhanced threefold through optimization of culture conditions. The optimum crude lipase activity was observed at 50 °C with high stability in a wide temperature range. The lipase also exhibited high activity and stability in the presence of solvents, metal ions, and surfactants. The crude lipase was used for the treatment of lipid-rich wastewater, which poses a significant challenge, as traditional removal methods are often inefficient or non-eco-friendly. In this study, bioaugmentation with Ant12 resulted in substantial lipid reduction in synthetic as well as real-world wastewater. Multiple linear regression analysis showed that lipid concentration and time were the most significant factors influencing lipid degradation. Bioaugmentation of real-world wastewater with Ant12 cells resulted in 84% removal of lipids in 72 h, while its crude lipase degraded 73.7% of lipids after 24 h. Thus, the specific rate of lipid degradation was higher for crude lipase (0.095/h) than the whole cell treatment (0.031/h). Economic analysis revealed that crude lipase production was much cheaper, faster and more eco-friendly than purified or partially purified lipase production, which justifies its use in wastewater treatment. The high activity of enzyme also implicates its application as a detergent additive. In our knowledge, it is the first study to establish A. johnsonii isolate from Antarctica for lipid-rich wastewater treatment.

Abstract
The effects of different concentrations of Hofmeister salts on the hydrolytic activity on triglycerides and the secondary structure of lipase B from Candida antarctica (CALB) were investigated. Structural changes after short- and long-time incubation at high salt concentrations were determined using circular dichroism (CD), fluorescence, and RMSD-RMSF simulations. At 5.2 M NaCl, the hydrolytic activity of CALB on tributyrin (TC4) and trioctanoin (TC8) was enhanced by 1.5 (from 817 ± 3.9 to 1228 ± 4.3 U/mg)- and 8.7 (from 25 ± 0.3 to 218 ± 2.3 U/mg)-folds compared with 0.15 M NaCl, respectively at pH 7.0 and 40 °C. An activity activation was seen with other salts tested; however, long-time incubation (24 h) did not result in retention of the activation effect for any of the salts tested. Secondary structure CD and fluorescence spectra showed that long-time incubation with NaCl, KCl, and CsCl provokes a compact structure without loss of native conformation, whereas chaotropic LiCl and CaCl2 induced an increase in the α-helical content, and kosmotropic Na2SO4 provoked a molten globule state with rich β-sheet content. The RMSD-RMSF simulation agreed with the CD analysis, highlighting a principal salt-induced effect at the α-helix 5 region, promoting two different conformational states (open and closed) depending on the type and concentration of salt. Lastly, an increase in the interfacial tension occurred when high salt concentrations were added to the reaction media, affecting the catalytic properties. The results indicate that high-salt environments, such as 2-5.2 M NaCl, can be used to increase the lipolytic activity of CALB on TC4 and TC8.

Abstract
Mannan, a highly abundant and cost-effective natural resource, holds great potential for the generation of high-value compounds such as bioactive polysaccharides and biofuels. In this study, we successfully enhanced the expression of constructed GH5 β-mannanase (TaMan5) from Trichoderma asperellum ND-1 by employing propeptide in Pichia pastoris. By replacing the α-factor with propeptide (MGNRALNSMKFFKSQALALLAATSAVA), TaMan5 activity was significantly increased from 67.5 to 91.7 U/mL. It retained higher activity in the presence of 20% ethanol and 15% NaCl. When incubated with a high concentration of mannotriose or mannotetraose, the transglycosylation action of TaMan5 can be detected, yielding the corresponding production of mannotetraose or mannooligosaccharides. Moreover, the unique mechanism whereby TaMan5 catalyzes the degradation of mannan into mannobiose involves the transglycosylation of mannose to mannotriose or mannotetraose as a substrate to produce a mannotetraose or mannopentose intermediate, respectively. Additionally, the production of soluble sugars from lignocellulose is a crucial step in bioethanol development, and it is noteworthy that TaMan5 could synergistically yield fermentable sugars from corn stover and bagasse. These findings offered valuable insights and strategies for enhancing β-mannanase expression and efficient conversion of lignocellulosic biomass, providing cost-effective and sustainable approaches for high-value biomolecule and biofuel production.

Abstract
Extracellular protein production is primarily preferred to facilitate the downstream processes in recombinant protein production. Secretion of recombinant proteins is mediated by the processing of signal peptides in their N-terminal portion by the secretory mechanism of host expression systems. These molecular elements involved in secretion are functionally interchangeable between different species and secretion sequence screening is one of the widely used approaches to improve extracellular protein production. In this study, α-mating and protein internal repeats (PIR) secretion sequences isolated from different yeasts (Kluyveromyces lactis, Kluyveromyces marxianus and Hansenula polymorpha) were tested in Pichia pastoris for the production of two different proteins (α-amylase and xylanase) and compared with the well-known secretory signals, S. cerevisiae α-mating factor (Sc-MF) and P. pastoris protein internal repeats PIR (PpPIR). The results obtained showed the potential of signal sequences tested. Among the tested peptides, the highest yields were achieved with H. polymorpha protein internal repeats (HpPIR) and K. lactis α-mating factor (Kl-MF) for xylanase and K. marxianus protein internal repeats (KmPIR) and K. lactis α-mating factor (Kl-MF) for amylase. In further studies, these sequences can be evaluated as alternatives in the production of different proteins in P. pastoris and in the production of recombinant proteins in different expression systems.

Abstract
BACKGROUND The budding yeast Komagataella phaffii (Pichia pastoris) is widely employed to secrete proteins of academic and industrial interest. For secretory proteins, signal peptides are the sorting signal to direct proteins from cytosol to extracellular matrix, and their secretion efficiency directly impacts the yields of the targeted proteins in fermentation broth. Although the α-mating factor (MF) secretion signal from S. cerevisiae, the most common and widely used signal sequence for protein secretion, works in most cases, limitation exists as some proteins cannot be secreted efficiently. As the optimal choice of secretion signals is often protein specific, more secretion signals need to be developed to augment protein expression levels in K. phaffii. RESULTS In this study, the secretion efficiency of 40 α-MF secretion signals from various yeast species and 32 endogenous signal peptides from K. phaffii were investigated using enhanced green fluorescent protein (EGFP) as the model protein. All of the evaluated α-MF secretion signals successfully directed EGFP secretion except for the secretion signals of the yeast D. hansenii CBS767 and H. opuntiae. The secretion efficiency of α-MF secretion signal from Wickerhamomyces ciferrii was higher than that from S. cerevisiae. 24 out of 32 endogenous signal peptides successfully mediated EGFP secretion. The signal peptides of chr3_1145 and FragB_0048 had similar efficiency to S. cerevisiae α-MF secretion signal for EGFP secretion and expression. CONCLUSIONS The screened α-MF secretion signals and endogenous signal peptides in this study confer an abundance of signal peptide selection for efficient secretion and expression of heterologous proteins in K. phaffii.

Abstract
Pichia pastoris has been recognized as an important platform for the production of various heterologous proteins in recent years. The strong promoter AOX1, induced by methanol, with the help of the α-pre-pro signal sequence, can lead to a high expression level of extracellular protein. However, this combination was not always efficient, as protein secretion in P. pastoris involves numerous procedures mediated by several cellular proteins, including folding assisted by endoplasmic reticulum (ER) molecular chaperones, degradation through ubiquitination, and an efficient vesicular transport system. Efficient protein expression requires the cooperation of various intracellular pathways. This article summarizes the process of protein secretion, modification, and transportation in P. pastoris. In addition, the roles played by the key proteins in these processes and the corresponding co-expression effects are also listed. It is expected to lay the foundation for the industrial protein production of P. pastoris. KEY POINTS: • Mechanisms of chaperones in protein folding and their co-expression effects are summarized. • Protein glycosylation modifications are comprehensively reviewed. • Current dilemmas in the overall protein secretion pathway of Pichia pastoris and corresponding solutions are demonstrated.

Abstract
Within the last two decades, the methylotrophic yeast Pichia pastoris (Komagataella phaffii) has become an important alternative to E. coli or mammalian cell lines for the production of recombinant proteins. Easy handling, strong promoters, and high cell density cultivations as well as the capability of posttranslational modifications are some of the major benefits of this yeast. The high secretion capacity and low level of endogenously secreted proteins further promoted the rapid development of a versatile Pichia pastoris toolbox. This chapter reviews common and new "Pichia tools" and their specific features. Special focus is given to expression strains, such as different methanol utilization, protease-deficient or glycoengineered strains, combined with application highlights. Different promoters and signal sequences are also discussed.

Abstract
Bioprocess, a biocatalysis-based technology, is becoming popular in many research fields and widely applied in industrial manufacturing. However, low bioconversion, low productivity, and high costs during industrial processes are usually the limitation in bioprocess. Therefore, many biocatalyst strategies have been developed to meet these challenges in recent years. In this review, we firstly discuss protein engineering strategies, which are emerged for improving the biocatalysis activity of biocatalysts. Then, we summarize metabolic engineering strategies that are promoting the development of microbial cell factories. Next, we illustrate the necessity of using the combining strategy of protein engineering and metabolic engineering for efficient biocatalysts. Lastly, future perspectives about the development and application of novel biocatalyst strategies are discussed. This review provides theoretical guidance for the development of efficient, sustainable, and economical bioprocesses mediated by novel biocatalysts.

Abstract
Azurin, which is a bacterial secondary metabolite has been attracted as a potential anticancer agent in recent years because induced death of cancer cells and inhibited their growth. In this study, the production of azurin under the control of the alcohol oxidase promoter which is frequently used in the Pichia pastoris expression system was performed. The azurin gene amplified from Pseudomonas aeruginosa genomic DNA and inserted into the pPICZαA was cloned in Escherichia coli cells. Then, a linearized recombinant vector was transferred to the P. pastoris X-33 cells. Antibiotic resistance test and colony PCR were performed for the selection of multicopy transformants. Protein expression capacities of selected transformants were compared at the end of 48 h incubation. Both extracellular and intracellular protein expressions were observed in all of them by Western blot analysis. The relative expression levels of both intracellular and extracellular protein that belongs to the first clone were higher than the others. On the other hand, it was seen that the 4th clone had the highest protein secretion ability. The molecular mass of the extracellular azurin protein which is produced by recombinant clones was found to be about 20 kDa. This is the first report on azurin expression in P. pastoris.

Abstract
Pectate lyases play an essential role in textiles, animal feed, and oil extraction industries. Pichia pastoris can be an ideal platform for pectate lyases production, and BspPel (a thermo-alkaline pectate lyase from Bacillus sp. RN1) was overexpressed by combined strategies, reaching 1859 U/mL in a 50 L fermentator. It displayed the highest activity at 80°C, and maintained more than 60% of the activity between 30 and 70°C for 1 h. It showed an optimal pH of 10.0, and exhibited remarkable stability over a wider pH range (3.0-11.0), retaining more than 80.0% of enzyme activity for 4 h. The Km and kcat of BspPel on PGA (polygalacturonic acid) was 2.19 g L–1 and 116.1 s–1, respectively. The activity was significantly enhanced by Ca2+, Mn2+, and Cu2+, and a slight increase was observed with the addition of Ba2+ and Mg2+. Scanning electron microscope was used to show the degumming efficiency of BspPel on ramie fibers. The loss weight was 9.2% when treated with crude enzyme supernatant and 20.8% when treated with the enzyme-chemical method, which was higher than the 14.2% weight loss in the positive control treated with 0.5% (w/v) NaOH alone. In conclusion, BspPel could be a good candidate for the ramie degumming industry.

Abstract
Pichia pastoris (syn. Komagataella phaffii) expression system has been widely used in heterologous protein production. PDI1 is the structural gene for Protein Disulfide Isomerase (PDI) and one of the main proteins in the endoplasmic reticulum (ER). It serves as a chaperone and helps in the formation, restoration and isomerization of disulfide bonds in nascent proteins. Overexpression of chaperone genes like PDI1, is one of the approaches to alleviate unfolded protein response (UPR) in multicopy clones of P. pastoris. However, it is not in a general scheme and these approaches are protein specific. The complete understanding of promoter region of PDI1 can give insights for better regulation of UPR. The aim of our work was to characterize promoter region of PDI1 gene and evaluate the possibility of their use for efficient expression of heterologous proteins. For this purpose, we used a reporter system based on the Candida antarctica lipase B (CalB) gene. The efficiency of PDI1 promoter was also compared with that of inducible promoter, AOX1, and the constitutive promoter, GAP, under different carbon sources like glucose, glycerol and methanol. The results appear that the PDI1 promoter may act as an UPR inducible promoter at high copy numbers of target gene. Therefore, we propose that the PDI1 promoter can be used for moderate expression of heterologous proteins in pathway engineering applications and also for overexpression of molecular chaperones.

Abstract
Secretory expression is most often desired but usually hampered by limitations of signal peptide processing and protein folding in the methylotrophic yeast Pichia pastoris. To alleviate such limitations, novel endogenous signal peptides (Dan4, Gas1, Msb2, and Fre2) and folding factors (Mpd1p, Pdi2p, and Sil1p) were predicted based on the reported P. pastoris secretome and genome. Their effects were investigated using three reporter proteins: yeast-enhanced green fluorescent protein (yEGFP), β-galactosidase (Gal) and cephalosporin C acylase (SECA), in comparison with the commonly used Saccharomyces cerevisiae alpha-mating factor pre-pro leader sequence (α-MF) or folding factors (Pdi1p, BiP, and Hac1p). The newly identified signal sequences were superior over α-MF for production of heterologous proteins. The signal peptide Msb2 increased the specific extracellular production of all reporter proteins, ranging from 1.5- to 8.0-fold, and Dan4 enhanced all total protein production up to 172-fold. Co-expression of folding factors exhibited a protein-specific effect on cell growth, transcription and expression of different reporter genes. All of the novel folding factors enhanced total production of SECA, and Sil1p performed best in the extracellular SECA production, showing a 3.3-fold increase. These novel signal peptides and folding factors can be used for promoting secretion of heterologous proteins in P. pastoris.

Abstract
The effect of gene dosage on the production of Candida antarctica lipase B (CalB) in the methylotrophic yeast Komagataella phaffii, at high densities in a simple medium containing crude glycerin as the sole carbon source, is described. The use of crude glycerin, the main by-product of biodiesel production from vegetable oils, will reduce the production cost of the bioprocess. Two K. phaffii strains were constructed with one or three copies of LipB, an optimized version of the gene encoding CalB under the control of the constitutive PPGK1 promoter. These two constructs were tested and compared on batches using minimal-salts medium with crude glycerin. The strain with three copies achieved a higher enzyme yield (48,760 U/L, 2.3-fold higher than the one-copy strain), with 42 g/L biomass, with no effects on growth.

Abstract
Host cell proteins are inevitable contaminants of biopharmaceuticals. Here, we performed detailed analyses of the host cell proteome of moss ( Physcomitrella patens) bioreactor supernatants using mass spectrometry and subsequent bioinformatics analysis. Distinguishing between the apparent secretome and intracellular contaminants, a complex extracellular proteolytic network including subtilisin-like proteases, metallo-proteases, and aspartic proteases was identified. Knockout of a subtilisin-like protease affected the overall extracellular proteolytic activity. Besides proteases, also secreted protease-inhibiting proteins such as serpins were identified. Further, we confirmed predicted cleavage sites of 40 endogenous signal peptides employing an N-terminomics approach. The present data provide novel aspects to optimize both product stability of recombinant biopharmaceuticals as well as their maturation along the secretory pathway. Data are available via ProteomeXchange with identifier PXD009517.

Abstract
Streptomyces griseus trypsin (SGT) possesses enzymatic properties similar to mammalian trypsins and has great potential applications in the leather processing, bioethanol, detergent and pharmaceutical industry. Here, a new strategy was reported for improving its stable, active secretory production through engineering of its propeptide and self-degradation sites. By rationally introducing hydrophobic mutations into the N-terminus of SGT Exmt (R145I), replacing the propeptide with FPVDDDDK and engineering the α-factor signal peptide, trypsin production (amidase activity) was improved to 177.85±2.83U·mL-1 in a 3-L fermenter (a 3.75-fold increase). Subsequently, all of the residues involved in autolysis that were identified by mass spectrometry were mutated and the resulting proteins were evaluated. In particular, the variant tbcf (K101A) demonstrated high stability and production (227.65±6.51U·mL-1 and 185.71±5.68mg·L-1, respectively). The recombinant strain constructed here has great potential for large-scale production of active trypsin.

[PMID: 29129652 DOI: 10.1016/j.biotechadv.2017.11.002] [Citation(s) in RCA: 220] [Impact Index Per Article: 31.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2017] [Revised: 10/16/2017] [Accepted: 11/06/2017] [Indexed: 11/24/2022]
Abstract
Pichia pastoris has been recognized as one of the most industrially important hosts for heterologous protein production. Despite its high protein productivity, the optimization of P. pastoris cultivation is still imperative due to strain- and product-specific challenges such as promoter strength, methanol utilization type and oxygen demand. To address the issues, strategies involving genetic and process engineering have been employed. Optimization of codon usage and gene dosage, as well as engineering of promoters, protein secretion pathways and methanol metabolic pathways have proved beneficial to innate protein expression levels. Large-scale production of proteins via high cell density fermentation additionally relies on the optimization of process parameters including methanol feed rate, induction temperature and specific growth rate. Recent progress related to the enhanced production of proteins in P. pastoris via various genetic engineering and cultivation strategies are reviewed. Insight into the regulation of the P. pastoris alcohol oxidase 1 (AOX1) promoter and the development of methanol-free systems are highlighted. Novel cultivation strategies such as mixed substrate feeding are discussed. Recent advances regarding substrate and product monitoring techniques are also summarized. Application of P. pastoris to the production of biodiesel and other value-added products via metabolic engineering are also reviewed. P. pastoris is becoming an indispensable platform through the use of these combined engineering strategies.

Abstract
The cofactor engineering strategy can relieve the metabolic stress induced by expression of recombinant protein in cellular metabolism related to cofactor and energy reactions. To study the effect of cofactor regeneration on recombinant protein expression, NADH oxidase (noxE) was engineered in P. pastoris expressing lipase B (GSCALB). Expression of noxE in P. pastoris (GSCALBNOX) increased NAD+ levels by 85% with a concomitant reduction in NADH/NAD+ ratio of 67% compared to GSCALB. The change in the redox level positively influenced the methanol uptake rate and made 34% augment in CALB activity. The decline in NADH level (44%) by noxE expression had lowered the adenylate energy charge (AEC) and ATP level in GSCALBNOX. In order to regenerate ATP in GSCALBNOX, adenylate kinase (ADK1) gene from S. cerevisiae S288c was co-expressed. Expression of ADK1 showed a remarkable increase in AEC and co-expression of both the genes synergistically improved CALB activity. This study shows the importance of maintenance of cellular redox homeostasis and adenylate energy charge during recombinant CALB expression in P. pastoris.

Abstract
In this investigation, oil extraction was performed in marine macroalgae Gracilaria edulis, Enteromorpha compressa and Ulva lactuca. The algal biomass was characterized by Scanning Electron Microscopy and Fourier Transform-Infra Red Spectroscopy. Six different pre-treatment methods were carried out to evaluate the best method for maximum oil extraction. Optimization of extraction parameters were performed and high oil yield was obtained at temperature 55°C, time 150min, particle size 0.10mm, solvent-to-solid ratio 6:1 and agitation rate 500rpm. After optimization, 9.5%, 12.18% and 10.50 (g/g) of oil extraction yield was achieved from the respective algal biomass. The rate constant for extraction was obtained as first order kinetics, by differential method. Stable intracellular Cal A and Cal B lipase producing recombinant Pichia pastoris was constructed and used as biocatalyst for biodiesel production. Comparative analysis of lipase activity and biodiesel yield was made with immobilized Candida antarctica lipase.

Abstract
The feruloyl esterase (FAE) gene EST1 from the basidiomycete Pleurotus sapidus was heterologously expressed in Escherichia coli and Pichia pastoris. Catalytically active recombinant Est1 was secreted using P. pastoris as a host. For expression in P. pastoris, the expression vector pPIC9K was applied. The EST1 gene was cloned with an N-terminal α-mating factor pre-pro sequence and expressed under the control of a methanol inducible alcohol oxidase 1 promotor. Est1 was purified to homogeneity using ion exchange and hydrophobic interaction chromatography. The recombinant Est1 showed optima at pH 5.0 and 50 °C, and released ferulic acid from saccharide esters and from the natural substrate destarched wheat bran. Substrate specificity profile and descriptor-based analysis demonstrated unique properties, showing that Est1 did not fit into the current FAE classification model. Transferuloylation synthesis of feruloyl-saccharide esters was proven for mono- and disaccharides.

Extracellular production of Pseudozyma (Candida) antarctica lipase B with genuine primary sequence in recombinant Escherichia coli. J Biosci Bioeng 2015; 121:303-9.

Abstract
An Escherichia coli expression system was established to produce recombinant extracellular Pseudozyma (Candida) antarctica lipase B (CALB). With the aim of producing the genuine CALB without additional amino acid residues, the mature portion of the CALB gene was fused seamlessly to a pelB signal sequence and expressed in E. coli BL21(DE3) using the pET system. Inducing gene expression at low temperature (20°C) was crucial for the production of active CALB; higher temperatures caused inclusion body formation. Prolonged induction for 48 h at 20°C allowed for the enzyme to be released into the culture medium, with more than half of the activity detected in the culture supernatant. A catalytically inactive CALB mutant (S105A) protein was similarly released, suggesting that the lipid-hydrolyzing activity of the enzyme was not the reason for the release. The CALB production level was further improved by optimizing the culture medium. Under the optimized conditions, the CALB in the culture supernatant amounted to 550 mg/L. The recombinant CALB was purified from the culture supernatant, yielding 5.67 mg of purified CALB from 50 mL of culture. N-terminal sequencing and ESI-MS analyses showed proper removal of the pelB signal sequence and the correct molecular weight of the protein, respectively, confirming the structural integrity of the recombinant CALB. The kinetic parameters towards p-nitrophenylbutyrate and the enantiomeric selectivity on rac-1-phenylethylacetate of the recombinant CALB were consistent with those of the authentic CALB. This is the first example of E. coli-based extracellular production of a CALB enzyme without extra amino acid residues.

Abstract
Background Itaconic acid is on the DOE (Department of Energy) top 12 list of biotechnologically produced building block chemicals and is produced commercially by Aspergillus terreus. However, the production cost of itaconic acid is too high to be economically competitive with the petrochemical-based products. Itaconic acid is generally produced from raw corn starch, including three steps: enzymatic hydrolysis of corn starch into a glucose-rich syrup by α-amylase and glucoamylase, fermentation, and recovery of itaconic acid. The whole process is very time-consuming and energy-intensive. Results In order to reduce the production cost, saccharification and fermentation were integrated into one step through overexpressing the glucoamylase gene in A. terreus under the control of the native PcitA promoter. The transformant XH61-5 produced higher itaconate titer from liquefied starch than WT. To further increase the titer by enhancing the secretion capacity of overexpressed glucoamylase, a stronger signal peptide was selected based on the major secreted protein ATEG_02176 (an acid phosphatase precursor) by A. terreus under the itaconate production conditions. Under the control of the stronger signal peptide, the transformant XH86-8 showed higher itaconate production level than XH61-5 from liquefied starch. The itaconate titer was further enhanced through a two-step process involving the vegetative and production phase, and the transformant XH86-8 produced comparable itaconate titer from liquefied starch to current one (~80 g/L) from saccharified starch hydrolysates in industry. The effects of the new signal peptide and the two-step process on itaconate production were investigated and discussed. Conclusions Itaconic acid could be efficiently produced from liquefied corn starch by overexpressing the glucoamylase gene in A. terreus, which will be helpful for constructing a highly efficient microbial cell factory for itaconate production and for further lowering the production cost of itaconic acid.

Abstract
Pichia pastoris is an established protein expression host mainly applied for the production of biopharmaceuticals and industrial enzymes. This methylotrophic yeast is a distinguished production system for its growth to very high cell densities, for the available strong and tightly regulated promoters, and for the options to produce gram amounts of recombinant protein per litre of culture both intracellularly and in secretory fashion. However, not every protein of interest is produced in or secreted by P. pastoris to such high titres. Frequently, protein yields are clearly lower, particularly if complex proteins are expressed that are hetero-oligomers, membrane-attached or prone to proteolytic degradation. The last few years have been particularly fruitful because of numerous activities in improving the expression of such complex proteins with a focus on either protein engineering or on engineering the protein expression host P. pastoris. This review refers to established tools in protein expression in P. pastoris and highlights novel developments in the areas of expression vector design, host strain engineering and screening for high-level expression strains. Breakthroughs in membrane protein expression are discussed alongside numerous commercial applications of P. pastoris derived proteins.

Abstract
Within the last two decades, the methylotrophic yeast Pichia pastoris has become an important alternative to E. coli or mammalian cell lines for the production of recombinant proteins. Easy handling, strong promoters, and high cell density cultivations as well as the capability of posttranslational modifications are some of the major benefits of this yeast. The high secretion capacity and low level of endogenously secreted proteins further promoted the rapid development of a versatile Pichia pastoris toolbox. This chapter reviews common and new "Pichia tools" and their specific features. Special focus is given to expression strains, such as different methanol utilization, protease-deficient or glycoengineered strains, combined with application highlights. Different promoters and signal sequences are also discussed.

Abstract
One of the reasons for limited heterologous protein secretion in Pichia pastoris is the suboptimal folding conditions inside the cell. The Hsp70 and Hsp40 chaperone families in the cytoplasm or the ER regulate the folding and secretion of heterologous proteins. Here, we have studied the effect of chaperones Ydj1p, Ssa1p, Sec63p and Kar2p on the secretory expression of Candida antarctica lipase B (CalB) protein. Expression of CalB in P. pastoris resulted in the induction of Kar2p secretion into the medium surpassing the retrieval capacity of the cell. Individual overexpression of Ydj1p, Ssa1p and Sec63p in recombinant P. pastoris increased CalB expression level by 1.6-, 1.4- and 1.4-fold respectively compared to the control strain harboring only the CalB gene. However, overexpression of Kar2p had a negative effect on the expression of CalB. Moreover, Western blot analysis indicated accumulation and secretion of Kar2p in the ER, Golgi and extracellular medium in the chaperone coexpression strains. When expressed in combinations such as Ydj1p-Ssa1p, Ydj1p-Sec63p, Kar2p-Ssa1p, Kar2p-Sec63p, the expression level of CalB was increased by 2.5-, 1.5-, 1.5- and 1.5-fold respectively. Contrastingly, the Kar2p-Ydj1p combination resulted in decreased CalB secretion in the supernatant. From these results, we conclude that overexpression of Kar2p is not required for the secretion of CalB. Also, our work confirmed the synergistic effect of Ssa1p and Ydj1p chaperones in the expression of CalB.
