Abstract
This review covers a group of non-covalently associated molecules, particularly proteins (NCAp), incorporated in the yeast cell wall (CW) with neither disulfide bridges with proteins covalently attached to polysaccharides nor other covalent bonds. Most NCAp, particularly Bgl2, are polysaccharide-remodeling enzymes. Either directly contacting their substrate or appearing as CW lipid-associated molecules, such as in vesicles, they represent the most movable enzymes and may play a central role in CW biogenesis. The absence of the covalent anchoring of NCAp allows them to be there where and when it is necessary. Another group of non-covalently attached to CW molecules are polyphosphates (polyP), the universal regulators of the activity of many enzymes. These anionic polymers are able to form complexes with metal ions and increase the diversity of non-covalent interactions through charged functional groups with both proteins and polysaccharides. The mechanism of regulation of polysaccharide-remodeling enzyme activity in the CW is unknown. We hypothesize that polyP content in the CW is regulated by another NCAp of the CW-acid phosphatase-which, along with post-translational modifications, may thus affect the activity, conformation and compartmentalization of Bgl2 and, possibly, some other polysaccharide-remodeling enzymes.

Abstract
Inorganic polyphosphates (polyP), according to literature data, are involved in the regulatory processes of molecular complex of the Saccharomyces cerevisiae cell wall (CW). The aim of the work was to reveal relationship between polyP, acid phosphatase Pho3p, and the major CW protein, glucanosyltransglycosylase Bgl2p, which is the main glucan-remodelling enzyme with amyloid properties. It has been shown that the yeast cells with deletion of the PHO3 gene contain more high molecular alkali-soluble polyP and are also more resistant to exposure to alkali and manganese ions compared to the wild type strain. This suggests that Pho3p is responsible for hydrolysis of the high molecular polyP on the surface of yeast cells, and these polyP belong to the stress resistance factors. The S. cerevisiae strain with deletion of the BGL2 gene is similar to the Δpho3 strain both in the level of high molecular alkali-soluble polyP and in the increased resistance to alkali and manganese. Comparative analysis of the CW proteins demonstrated correlation between the extractability of the acid phosphatase and Bgl2p, and also revealed a change in the mode of Bgl2p attachment to the CW of the strain lacking Pho3p. It has been suggested that Bgl2p and Pho3p are able to form a metabolon or its parts that connects biogenesis of the main structural polymer of the CW, glucan, and catabolism of an important regulatory polymer, polyphosphates.

Appl Microbiol Biotechnol 2021; 106:663-673. [PMID: 34971409 DOI: 10.1007/s00253-021-11750-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 12/10/2021] [Accepted: 12/14/2021] [Indexed: 11/25/2022]
Abstract
For the efficient production of heterologous proteins in the yeast Saccharomyces cerevisiae, we screened for a novel fusion partner from the yeast secretome. From twenty major proteins identified from the yeast secretome, we selected Scw4p, a cell wall protein with similarity to glucanase, and modified to develop a general fusion partner for the secretory expression of heterologous proteins in yeast. The optimal size of the SCW4 gene to act as an efficient fusion partner was determined by C-terminal truncation analysis; two of the variants, S1 (truncated at codon 115Q) and S2 (truncated at codon 142E), were further used for the secretion of heterologous proteins. When fused with S2, the secretion of three target proteins (hGH, exendin-4, and hPTH) significantly increased. Conserved O-glycosylation sites (Ser/Thr-rich domain) and hydrophilic sequences of S2 were deemed important for the function of S2 as a secretion fusion partner. Approximately 5 g/L of the S2-exendin-4 fusion protein was obtained from fed-batch fermentation. Intact target proteins were easily purified by affinity chromatography after in vitro processing of the fusion partner. This system may be of general application for the secretory production of heterologous proteins in S. cerevisiae. KEY POINTS : • Target proteins were efficiently secreted with their N-terminus fused to Scw4p. • O-glycosylation and hydrophilic stretches in Scw4p were important for protein secretion. • A variant of Scw4p (S2) was successfully applied for the secretory expression of heterologous proteins.
