The Stability

Levan has wide applications in chemical, cosmetic, pharmaceutical and food industries. The free levansucrase is usually used in the biosynthesis of levan, but the poor reusability and low stability of free levansucrase have limited its large-scale use. To address this problem, the surface-displayed levansucrase in Saccharomyces cerevisiae were generated and evaluated in this study. The levansucrase from Zymomonas mobilis was displayed on the cell surface of Saccharomyces cerevisiae EBY100 using a various yeast surface display platform. The N-terminal fusion partner is based on a-agglutinin, and the C-terminal one is Flo1p. The yield of levan produced by these two whole-cell biocatalysts reaches 26 g/L and 34 g/L in 24 h, respectively. Meanwhile, the stability of the surface-displayed levansucrases is significantly enhanced. After six reuses, these two biocatalysts retained over 50% and 60% of their initial activities, respectively. Furthermore, the molecular weight and polydispersity test of the products suggested that the whole-cell biocatalyst of levansucrase displayed by Flo1p has more potentials in the production of levan with low molecular weight which is critical in certain applications. In conclusion, our method not only enable the possibility to reuse the enzyme, but also improves the stability of the enzyme.

ABSTRACTBrain-derived neurotrophic factor (BDNF) plays an important role in nervous system function and has therapeutic potential. Microbial production of BDNF has resulted in a low-fidelity protein product, often in the form of large, insoluble aggregates incapable of binding to cognate TrkB or p75 receptors. In this study, employingSaccharomyces cerevisiaedisplay and secretion systems, it was found that BDNF was poorly expressed and partially inactive on the yeast surface and that BDNF was secreted at low levels in the form of disulfide-bonded aggregates. Thus, for the purpose of increasing the compatibility of yeast as an expression host for BDNF, directed-evolution approaches were employed to improve BDNF folding and expression levels. Yeast surface display was combined with two rounds of directed evolution employing random mutagenesis and shuffling to identify BDNF mutants that had 5-fold improvements in expression, 4-fold increases in specific TrkB binding activity, and restored p75 binding activity, both as displayed proteins and as secreted proteins. Secreted BDNF mutants were found largely in the form of soluble homodimers that could stimulate TrkB phosphorylation in transfected PC12 cells. Site-directed mutagenesis studies indicated that a particularly important mutational class involved the introduction of cysteines proximal to the native cysteines that participate in the BDNF cysteine knot architecture. Taken together, these findings show that yeast is now a viable alternative for both the production and the engineering of BDNF.

Anchor Proteins

Yeast surface display has become an increasingly popular tool for protein engineering and library screening applications. Although, recent advances have greatly expanded the capability of yeast surface display, the protein display system is still far away from industrial application. One of the major components of a stable, efficient and successful yeast surface display system is cell wall anchor protein with which our desired foreign protein will be attached. We studied 80 different yeast cell wall anchored proteins originated mostly from Saccharomyces cerevisiae and Candida albicans. We studied in details all the cell wall proteins in order to find out suitable cell wall proteins to recommend for the researchers to use in the construction of yeast display system. We considered selective physical properties of different yeast cell wall proteins that are crucial for selecting best suited cell surface anchor proteins which are molecular weight, binding domain of anchor protein, length of amino acid and fusion site. Finally, our studies showed that Ccw11, Ccw12. Cwp1, Cwp2, Dan1, Gas1, Gas5, Exg1, Ycr89, Ecm33, Pga4, Sap9, Sap10, Pst1, Pir1, Pir2, Pir3, Pir4, Cis1, Scw4, Scw6, Bgl2, Uth1, Scw1 are the promising and suitable cell wall anchor proteins could be used in construction of yeast cell surface display system. Additionally, this review presents detailed information about all the cell wall proteins in a single work. The future researchers in this field will be able to construct more efficient yeast display system for recombinant protein production at industrial scale using the knowledge presented in this work.
