[Different composition of the cell wall polysaccharides in Saccharomyces cerevisiae S288 and in an osmosis sensitive mutant].
Determination of the polysaccharide contents and structural studies on the mannan by acetolysis and permethylation analysis shows an altered polysaccharide biosynthesis of the osmotic-sensitive mutant VY 1160 of Saccharomyces cerevisiae S 288. The mutant contains more glucan, less mannan, and less alkali-soluble glycogen. Its mannan is characterized by more short side chains and less long side chains. Its main chain is 1 leads to 6-linked, but its side chains consist of more 1 leads to 3- than 1 leads to 2-linked mannose units.
