Biosynthesis of glycerol teichoic acid in Bacillus cereus: Formation of linkage unit disaccharide on a lipid intermediate
Search this article
Description
Abstract A tunicamycin-like antibiotic 24010 at a concentration of 1 μg/ml selectively inhibited the in vivo synthesis of glycerol teichoic acid of cell walls in Bacillus cereus AHU 1030. Incubation of membranes of this strain with N -acetylglucosaminyl pyrophosphorylundecaprenol and UDP- N -acetylmannosamine led to formation of a glycolipid having a saccharide moiety identical with the cell wall teichoic acid linkage unit, N -acetylmannosaminylβ(1→4)- N -acetylglucosamine. The membranes also catalyzed transfer of glycerol phosphate units from CDP-glycerol to this disaccharide-linked lipid. Thus the biosynthesis of the cell wall glycerol teichoic acid in this strain seems to involve the disaccharide-linked lipid as an intermediate.
