Schizosaccharomyces pombe polysaccharide

A mixture of polysaccharides, including a galactomannan, (1 3)-a-D-glucan, and a branched (1 - 3)-P-D-glucan, has been extracted with dilute alkali from the cell walls of Schizosaccharomyces pombe. The alkali-insoluble residue contained a lightly branched (1 3)-P-Drglucan and small amounts of an extremely... 

On the basis of the n.m.r. spectra, various structural assignments have been made to polysaccharides of S. schenkii, including a neutral mono-L-rhamnosyl-D-mannan and an acidic L-rhamno-D-mannan. Many strains from species of Sporothrix, Ceratocystis, Europhium, and Graphium have exhibited serological cross-reactions with S. schenckii, and contain polysaccharides composed of residues of L-rhamnose and D-mannose. The d-galacto-D-mannan of Schizosaccharomyces pombe has been located at the periphery of the cell wall and near the plasmalemma. No evidence was obtained for the presence of chitin.
