TY - JOUR. T1 - Improvement in the secretory expression of recombinant Candida rugosa lipase in Pichia pastoris. AU - Kuo, Ting Chun. AU - Shaw, Jei Fu. AU - Lee, Guan Chiun. PY - 2015/12/1. Y1 - 2015/12/1. N2 - The yeast Candida rugosa can secrete a mixture of lipase isoenzymes (Lips), which have been widely applied in industry. Eight Lip genes (LIP1 to LIP8) have been identified and are expressed in Pichia pastoris. However, the expression level was not sufficient for economical industrial application. In this study, two combined processes of antibiotic selection and low-temperature culture efficiently elicited a high-level secretion of recombinant Lip2 in P. pastoris. The LIP2 gene copy number of the Pichia transformants was increased by sequential selections at gradually increasing Zeocin concentrations. After the first selection at 500 μg/mL of Zeocin, three clones (500-clones) with 2.4-fold to 5.8-fold improvement in Lip2 secretion were identified from 105 survival clones through lipase ...

N2 - A system of expression for the foreign actin gene in yeast cells Pichia pastoris has been developed. As a target protein, the Drosophila cytoplasmic actin 5C, which has 90% homology to the β-actin of higher eukaryotes, was used. In the present work, in order to develop conditions for biosynthesis of the target protein in yeast cells and a purification procedure for the recombinant protein, a GFP-actin fusion protein containing green fluorescent protein (GFP) as a fusion tag was expressed and purified. The size and survival of P. pastoris cells producing recombinant protein were characterized and shown to depend on the accumulation of recombinant ...

In Saccharomyces cerevisiae the activity for the lactate-proton symporter is dependent on JEN1 gene expression. Pichia pastoris was transformed with an integrative plasmid containing the JEN1 gene. After 24 h of methanol induction, Northern and Western blotting analyses indicated the expression of JEN1 in the transformants. Lactate permease activity was obtained in P. pastoris cells with a Vmax of 2.1 nmol·s−1·mg of dry weight−1. Reconstitution of the lactate permease activity was achieved by fusing plasma membranes of P. pastoris methanol-induced cells with Escherichia coli liposomes containing cytochrome c oxidase, as proton-motive force. These assays in reconstituted heterologous P. pastoris membrane vesicles demonstrate that S. cerevisiae Jen1p is a functional lactate transporter. Moreover, a S. cerevisiae strain deleted in the JEN1 gene was transformed with a centromeric plasmid containing JEN1 under the control of the glyceraldehyde-3-phosphate dehydrogenase constitutive promotor. ...
Here we describe a new technical solution for optimization of Pichia pastoris shake flask cultures with the example of production of stable human type II collagen. Production of recombinant proteins in P. pastoris is usually performed by controlling gene expression with the strong AOX1 promoter, which is induced by addition of methanol. Optimization of processes using the AOX1 promoter in P. pastoris is generally done in bioreactors by fed-batch fermentation with a controlled continuous addition of methanol for avoiding methanol toxification and carbon/energy starvation. The development of feeding protocols and the study of AOX1-controlled recombinant protein production have been largely made in shake flasks, although shake flasks have very limited possibilities for measurement and control. By applying on-line pO2 monitoring we demonstrate that the widely used pulse feeding of methanol results in long phases of methanol exhaustion and consequently low expression of AOX1 controlled genes. Furthermore, we

Methylotrophic yeast species (e.g. Hansenula polymorpha, Pichia pastoris) can grow on methanol as sole source of carbon and energy. These organisms are important cell factories for the production of recombinant proteins, but are also used in fundamental research as model organisms to study peroxisome biology. During exponential growth on glucose, cells of H. polymorpha typically contain a single, small peroxisome that is redundant for growth while on methanol multiple, enlarged peroxisomes are present. These organelles are crucial to support growth on methanol, as they contain key enzymes of methanol metabolism. In this study, changes in the transcriptional profiles during adaptation of H. polymorpha cells from glucose- to methanol-containing media were investigated using DNA-microarray analyses. Two hours after the shift of cells from glucose to methanol nearly 20% (1184 genes) of the approximately 6000 annotated H. polymorpha genes were significantly upregulated with at least a two-fold differential

Inulin is linear oligosaccharides [1]. Although inulin can be hydrolyzed to monosaccharides non-enzymatically by acid treatment, inhibitory by-products produced that complicate downstream biological process. Therefore, it is pivotal to establish a cost-effective inulinase (EC 3.2.1.7) production. In this study, we isolated the DNA sequence encoding the mature peptide sequence of the exo-inulinase gene from Kluyveromyces marxianus CBS 6556 and expressed in Pichia pastoris X-33. The purified recombinant enzyme (reINU) gave a specific activity of 13100 U•mg−1, which was about 100-fold higher that reported for the wild type protein isolated from K. marxianus CBS6556 [2, 3]. Ferguson plot analysis showed that secretion expressed reINU was a 169 kDa dimer. Detailed analytical assays showed that the optimal temperature and pH for reINU were 60 oC and pH 4.0, respectively. It was found that hydrolysis activity was about 20% higher in the presence of Mn2+. reINU was stable for over 3 days at room ...
A lipase gene (atl) was cloned from Aspergillustamarii FS132 for the first time. The gene was found to have an open reading frame of 1024 base pairs (bp), and the coding region of the gene contained two introns (51 bp and 52 bp). Multi-alignment analysis of the deduced amino acid sequence indicated high homology between the enzyme and mono- and diacylglycerol lipases from fungi Aspergillus. The recombinant lipase was expressed in Pichia pastoris GS115 cells. The recombinant lipase was found to have a molecular mass of 36.7 kDa, and it exhibited lipase activity of 20 U/mL in culture supernatant when tributyrin was used as the substrate.

With a variety of physiological and pharmacological functions, menaquinone is an essential prenylated product that can be endogenously converted from phylloquinone (VK1) or menadione (VK3) via the expression of Homo sapiens UBIAD1 (HsUBIAD1). The methylotrophic yeast, Pichia pastoris, is an attractive expression system that has been successfully applied to the efficient expression of heterologous proteins. However, the menaquinone biosynthetic pathway has not been discovered in P. pastoris. Firstly, we constructed a novel synthetic pathway in P. pastoris for the production of menaquinone-4 (MK-4) via heterologous expression of HsUBIAD1. Then, the glyceraldehyde-3-phosphate dehydrogenase constitutive promoter (PGAP) appeared to be mostsuitable for the expression of HsUBIAD1 for various reasons. By optimizing the expression conditions of HsUBIAD1, its yield increased by 4.37 times after incubation at pH 7.0 and 24 °C for 36 h, when compared with that under the initial conditions. We found HsUBIAD1

Production of heterologous proteins in yeast becomes more and more important in the biotechnological sector for research use, therapeutics or sustainable energy sources [1, 2]. This development has led to the constant demand for improvement of hosts and processes for recombinant protein production (RPP). Common approaches for improvement of RPP are mostly based on strain engineering [3], process optimization [4] including adaptation of culture conditions [5-8], feed strategies [9], or media optimization [10, 11]. As production processes become more and more specific due to special needs of production hosts [11] and the recombinant product, media need to be developed for a specific process and are often tailor-made [12]. In general, cultivation media should be chemically defined, however, high level protein synthesis, influencing cell physiology, might make supplementation with e.g. amino acids necessary [13]. For bioreactor cultivations of the yeast production host Pichia pastoris (Komagataella ...
ABSTRACT: BACKGROUND: Inducible high-level expression is favoured for recombinant protein production in Pichia pastoris. Therefore, novel regulated promoters are desired, ideally repressing heterologous gene expression during initial growth and enabl
Expanding the application of technical enzymes, e.g., in industry and agriculture, commands the acceleration and cost-reduction of bioprocess development. Microplates and shake flasks are massively employed during screenings and early phases of bioprocess development, although major drawbacks such as low oxygen transfer rates are well documented. In recent years, miniaturization and parallelization of stirred and shaken bioreactor concepts have led to the development of novel microbioreactor concepts. They combine high cultivation throughput with reproducibility and scalability, and represent promising tools for bioprocess development. Parallelized microplate cultivation of the eukaryotic protein production host Pichia pastoris was applied effectively to support miniaturized phenotyping of clonal libraries in batch as well as fed-batch mode. By tailoring a chemically defined growth medium, we show that growth conditions are scalable from microliter to 0.8 L lab-scale bioreactor batch cultivation ...

The methylotrophic yeast P. pastoris has, during the last decades, increased in popularity as a eukaryotic host for recombinant protein expression [7]. Numerous reports have described successful overexpression of soluble proteins as well as of membrane proteins in this system, but sufficient protein yields have not always been obtained. Several methods have been described that could be used to improve the outcome of expression trials, among which an optimisation of recombinant gene dosage has proven to be one of the most potent ones [21]. When it comes to the aquaporin family of membrane proteins, optimisation of the nucleotide sequence both regarding codon composition and AT content [38] and controlled growth in bioreactors [36] have been reported to improve the yields of heterologous protein. However, in no reports has a systematic examination of the effect of gene dosage on recombinant aquaporin expression in P. pastoris been done and results obtained for other membrane proteins [12, 15, 33] ...
Advanced tumor growth is angiogenesis dependent (27) and endothelial cell organization into vascular networks is a hallmark of the angiogenic process (28). Such organization involves the mobilization of endothelial cells from a quiescent state to form a quasi-mature vasculature that can supply the growing mass with nutrients and oxygen (28). Inhibition of endothelial cell tube formation by endostatin may be due (at least in part) to blockade of the endothelial cells mobilization stimuli, although it is unclear whether this inhibition requires direct interaction with the endothelial cell or other cells that provide the required stimulatory cytokines. Surprisingly, endostatin obtained from EntreMed or Calbiochem had different efficacy profiles in our endothelial cell tube formation assays. This observation was unexpected given that EntreMed produces human endostatin in a P. pastoris expression system and supplies it to Calbiochem for packaging and sale. Follow-up experiments were conducted to ...
Recombinant protein production lies at the core of the biotechnology revolution. Recombinant proteins such as humanized chimeric antibodies, human growth hormone, human insulin and a variety of industrial enzymes can been expressed in the yeast Pichia pastoris, a premier organism for eucaryotic protein expression. Pichia pastoris grows rapidly on inexpensive substrates to very high cell densities, and can produce biologically active foreign proteins of higher eukaryotic origin since it performs important posttranslational protein modifications, including proteolytic processing, disulfide bridge formation and glycosylation.. Regenerative medicine is aimed at using biological solutions to restore function to damaged or diseased biological systems. Work in this field could potentially yield viable tissues or organs for replacement, as well as therapies for a number of diseases. Stem cell therapies and gene therapy are among the most promising research avenues in regenerative medicine. Stem cells ...
Fibroblast Growth Factor 21 (FGF21) is a novel target with potential anti diabetic properties that are useful for treatment of hyperglycemia, insulin resistance, hyperlipidemia and metabolic disease. Producing recombinant FGF21 by E. coli without using fusion proteins is time consuming and will produce low quantity products. In this study, to establish and test the efficiency of other expression methods, the complete fgf21 gene was constructed by overlapping PCR. The recombinant fgf21 genes were expressed successfully in E. coli (TB1) and in yeast (Pichia pastoris) under the control of maltose binding promoter and alcohol oxidase I promoter. The degree of success in terms of yield and functionality of the produced recombinant proteins in vivo were compared by using animal models. The result demonstrated that both expression systems can promote more soluble FGF21 levels, with less purification steps while preserving the bioactivity of the protein in vivo. The FGF21 produced in P. pastoris ...

[more ▼]. High Pichia pastoris biomass density could be obtained using high co-feeding rate of methanol and sorbitol in a fed-batch or continuous culture, while further higher feeding rate finally leads to oxygen limitation in bioreactor. In the literature, there is lack of report about AOX1 promoter regulation with regard to dissolved oxygen level (DO). Therefore, in this work, chemostat cultures were performed to investigate the cell growth, metabolism and regulation of the AOX1 promoter (pAOX1) regarding co-feeding rate of optimized methanol/sorbitol mixture (methanol fraction 0.60 C-mol/C-mol) using a P. pastoris Mut+/pAOX1-lacZ strain. The oxygen transfer rates (OTR) in bioreactor were kept in the range of ...
Saccharomyces cerevisiae and Pichia pastoris are two of the most relevant microbial eukaryotic platforms for the production of recombinant proteins. Their known genome sequences enabled several transcriptomic profiling studies under many different environmental conditions, thus mimicking not only perturbations and adaptations which occur in their natural surroundings, but also in industrial processes. Notably, the majority of such transcriptome analyses were performed using non-engineered strains. In this comparative study, the gene expression profiles of S. cerevisiae and P. pastoris, a Crabtree positive and Crabtree negative yeast, respectively, were analyzed for three different oxygenation conditions (normoxic, oxygen-limited and hypoxic) under recombinant protein producing conditions in chemostat cultivations. The major differences in the transcriptomes of S. cerevisiae and P. pastoris were observed between hypoxic and normoxic conditions, where the availability of oxygen strongly affected
I have a recombinant protein produced in the yeast Pichia pastoris that is partially glycosylated with O-linked sugar (it must be O-linked - there are no N-linked sites). I wish to remove the glycosylated protein from the non-glycosylated. I have tried using ConA-Sepharose (Pharmacia) and Glycine-Max (Sigma). Neither of these has appeared to bind. The ConA comes with instructions that have been followed. No instructions could be found for Gycine-MAx and Sigma were not forthcoming. Has anyone has experience with trying to purify O-linked sugars, with either of the above lectins, or using any other reagents, I would very much like to hear from you.

1B3E: X-ray crystallography and mass spectroscopy reveal that the N-lobe of human transferrin expressed in Pichia pastoris is folded correctly but is glycosylated on serine-32.
A major bottleneck in structural, biochemical and biophysical studies of proteins is the need for large amounts of pure homogenous material, which is generally obtained by recombinant overexpression. Here we introduce a vector collection, the pCri System, for cytoplasmic and periplasmic/extracellular expression of heterologous proteins that allows the simultaneous assessment of prokaryotic and eukaryotic host cells (Escherichia coli, Bacillus subtilis, and Pichia pastoris). By using a single polymerase chain reaction product, genes of interest can be directionally cloned in all vectors within four different rare restriction sites at the 5′end and multiple cloning sites at the 3′end. In this way, a number of different fusion tags but also signal peptides can be incorporated at the N-and C-terminus of proteins, facilitating their expression, solubility and subsequent detection and purification. Fusion tags can be efficiently removed by treatment with site-specific peptidases, such as tobacco ...
P. pastoris and E. coli are commonly used hosts for recombinant product expression because of their ability to produce large quantities of recombinant protein quickly and economically. P. pastoris can express proteins with correct primary, secondary and tertiary structure and post-translational modifications such as glycolysation, proteolytic processing and disulfide bond formation. E. coli are readily transformed and can express large quantities of proteins quickly with correct primary structure in the soluble or insoluble forms. These attributes ensure that each host will remain central in recombinant protein expression of the future ...

While there has been some research done on novel proteins, the information is far from being comprehensive and is done in isolation. Some scientists are researching the nutritional quality of peas, others are breeding new dry beans varieties, while others are investigating processing methods for canola. By combining individual efforts and ideas, we can do more and reach attainable goals faster. The PPIC will invite scientists both internal and external to the University of Minnesota to be part of a research cohort. Collaboration will empower plant-based protein research by allowing scientists to come together to think beyond their area of focus. Working together will facilitate cross-lab use of high-end instrumentation that can uncover more information than ever before, and will open up larger grant opportunities. Partnering with industry is essential. The PPIC requires the support of key industry players, who are driven to work together towards a better future. Industry partners, will be ...

Yeast Pichia stipitis CBS 5776 was developed through adaptation fermentation step by step in steam exploded corn stover prehydrolyzate because high concentration of weak acids and other inhibitors present in the prehydrolyzate could degrade the fermentability. However, the adaptability of Pichia stipitis CBS 5776 in the prehydrolyzate was so limited that steam strip-ping and overliming were applied to remove these inhibitors from it. Corn stover was steam exploded; the filtrate of steam exploded corn stover was hydrolyzed with dilute sulfuric acid, and then the acid hydrolyzate was detoxified and fermented by Pichia stipitis CBS 5776. Steam stripping could remove volatile com-pounds from the acid hydrolyzate and the fil-trate. At a steam stripping time of 120min, 81% acetic acid and 59% formic acid were removed from the acid hydrolyzate, 77% acetic acid and 45% formic acid were removed from the filtrate, while furfural was stripped off completely from the acid hydrolyzate and the filtrate. Overliming
