Exploring improved endoglucanase expression in Saccharomyces cerevisiae strains

Du Plessis L. Rose S.H. Van Zyl W.H. (2010)

The endoglucanase I and II genes (egI or Cel7B and egII or Cel5A) of Trichoderma reesei QM6a were successfully cloned and expressed in Saccharomyces cerevisiae under the transcriptional control of the yeast ENO1 promoter ...

FLO gene-dependent phenotypes in industrial wine yeast strains

Govender P. Bester M. Bauer F.F. (2010)

Most commercial yeast strains are nonflocculent. However, controlled flocculation phenotypes could provide significant benefits to many fermentation-based industries. In nonflocculent laboratory strains, it has been ...

Functional analysis of the Zygosaccharomyces rouxii Fps1p homologue

Tang X.-M. Kayingo G. Prior B.A. (2005)

The osmotolerant yeast Zygosaccharomyces rouxii accumulates the polyols glycerol and D-arabitol intracellularly in response to hyperosmotic stress, but the membrane transport proteins regulating polyol accumulation have ...

Toh T.-H. Kayingo G. Van Der Merwe M.J. Kilian S.G. Hallsworth J.E. Hohmann S. Prior B.A. (2001)

The deletion of the gene encoding the glycerol facilitator Fps1p was associated with an altered plasma membrane lipid composition in Saccharomyces cerevisiae. The S. cerevisiae fps1Δ strain respectively contained 18 and ...

Isolation and characterization of the TIM10 homologue from the yeast Pichia sorbitophila a putative component of the mitochondrial protein import system

Kayingo G. Potier S. Hohmann S. Prior B.A. (2000)

The Saccharomyces cerevisiae TIM10 gene encodes one of the few essential mitochondrial proteins that are required for the import of nuclear-encoded precursor proteins from the cytosol and their subsequent sorting into the ...

Molecular analysis of a Saccharomyces cerevisiae mutant with improved ability to utilize xylose shows enhanced expression of proteins involved in transport, initial xylose metabolism, and the pentose phosphate pathway

Wahlbom C.F. Cordero Otero R.R. Van Zyl W.H. Hahn-Hagerdal B. Jonsson L.J. (2003)

Differences between the recombinant xylose-utilizing Saccharomyces cerevisiae strain TMB 3399 and the mutant strain TMB 3400, derived from TMB 3399 and displaying improved ability to utilize xylose, were investigated by ...

MSS11, a novel yeast gene involved in the regulation of starch metabolism

Webber A.L. Lambrechts M.G. Pretorius I.S. (1997)

Expression of the STA1-3 glucoamylase genes, responsible for starch degradation in Saccharomyces cerevisiae, is down regulated by the presence of STA10. In order to elucidate the role of STA10 in the regulation of the ...

Regulation of endo-polygalacturonase activity in Saccharomyces cerevisiae

Louw C. Young P.R. Van Rensburg P. Divol B. (2010)

Pectolytic activity in Saccharomyces cerevisiae is due to the secretion of an endo-polygalacturonase encoded by the PGU1 gene. The ability to degrade polygalacturonic acid has been shown to vary between different strains. ...
