The presence of dolichol in a lipid diphosphate N-acetylglucosamine from Saccharomyces cerevisiae (baker's yeast).
Ontology highlight
ABSTRACT: The lipid moiety of a lipid diphosphate N-acetylglucosamine, an intermediate in glycosylation of proteins, was studied. Ozonolysis of the compound gave evidence for an alpha-saturated isoprene unit. Alkaline hydrolysis of the glycolipid, followed by high-pressure liquid chromatography, showed the presence of a series of polyprenol homologues identical with those isolated directly from Saccharomyces cerevisiae (baker's yeast). No particular homologue was preferred in the enzymic transfer of N-acetylglucosamine 1-phosphate to endogenous dolichol monophosphate.
