A mannitol teichoic acid containing rhamnose and pyruvic acid acetal from the cell wall of Brevibacterium permense VKM Ac-2280

摘要

The cell wall of Brevibacterium permense VKM Ac-2280 contains tow teichoic acids.The major polymer represents a 1,6-poly (mannitol phosphate) substituted wirh either L-rhamnose (approx 70%,unit A) or (S)-acetal of pyruvic acid (approx 30%,unit B) with the overall chain length approx 10 mannitol phosphate units.The other polymer is an unsubstituted 1,3-poly (glycerol phosphate).The structures of the polymers were established using chemical degradations and NMR spectroscopy.The data obtained may be helpful in determination of the species-specific status of newly isolated Brevibacterium strains.
