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

Abstract

The cell wall of Brevibacterium permense VKM Ac-2280 contains two teichoic acids. The major polymer represents a 1,6-poly(mannitol phosphate) substituted wirh either l-rhamnose (∼70%, unit A) or ( S)-acetal of pyruvic acid (∼30%, unit B) with the overall chain length ∼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.
