Bakers’ yeast Saccharomyces cerevisiae

The computational approach described above has been applied to the bakers yeast Saccharomyces cerevisiae) genome, and approximately 50 known and... 

GFP has also been proposed as a successor to the Ames and SOS chromotest. Billinton et al. [8] obtained a reporter system, employed as genotoxicity biosensor, that uses eukaryotic cells (the baker yeast Saccharomyces cerevisiae) instead of bacteria. The strain produces green fluorescent protein, codon optimized for yeast, when DNA damage has occurred. It was demonstrated that the reporter does not falsely respond to chemicals that delay mitosis, and responds appropriately to the genetic regulation of DNA repair.

The bakers yeast Saccharomyces cerevisiae represents probably the currently best researched and understood eukaryotic organism. Most of its genes have been knocked out for functional studies, and hence a vast variety of mutant strains as well as tools for their manipulation are available. This in concordance with short generation times and a growth medium that is comparable in cost and complexity to bacterial media has made the yeast system a frequent choice for the evaluation of transmembrane carriers. 

Yeast mannan, commonly known as yeast gum by early workers, was first isolated in a pure form by Salkowski. It was extracted from pressed bakers yeast (Saccharomyces cerevisiae) with hot, aqueous alkali, and separated from such contaminants as glycogen through the insoluble, copper complex formed with Fehling solution. Mundkur has presented evidence indicating that a layer of mannan... 

Mannan was discovered in bakers yeast (Saccharomyces cerevisiae) by Salkowski in 1894 at that time, it was termed yeast gum. The first detailed studies of its structure were made by the methyl-ation procedure by Haworth and coworkers. - The results showed that the polysaccharide consists entirely of D-mannose residues and is highly branched, the D-mannose residues being combined by (1 2)-, (1 3)-, and (1 — 6)-linkages. Its molecular weight, as... 

The enantioselective production of ephedrine belongs to the earliest industrial examples of biocatalysis. Around 1920, Carl Neuberg (1877-1956) had discovered at the Kaiser-Wdhelm-lnstitut in Berlin, that pyruvate-decarboxylase in bakers yeast Saccharomyces cerevisiae) converted benzaldehyde with acetalde-... 

Isol. from the partial acid hydrolysate of bakers yeast (Saccharomyces cerevisiae) mannan and of Candida utilis mannan. [a]o +68 (c, 0.42 in H2O). 

One of the yeasts, which were investigated the best, is the common bakers yeast, Saccharomyces cerevisiae, for which both complete genome and detailed protein data sets are available. S. cerevisiae contains a relatively simple, but conserved network of lipid metabolism/catabohsm pathways. This network controls the synthesis of hundreds of lipid molecular species [1], and therefore its full lipidome. As compared in Chapter 16, the biosynthesis and metabohsm of GPLs in the yeasts are very similar to those of higher eukaryotes, with three main exceptions. 

Steiner et al. (1969) observed, that the major inositol containing lipid from bakers yeast Saccharomyces cerevisiae) upon treatment with acid or alkali lost one phosphoryl-inositol group and yielded mannosyl-inositol-phosphoryl-ceramide. The authors discussed for the original material the composition Man-(In-phosphoryl)2-cer.
