Abstract
The structure of the polysaccharide O-chain of the lipopolysaccharide isolated from the sequenced strain Chromobacterium violaceum ATCC 12472 (NCTC 9757) was investigated by chemical and NMR analyses, and concluded to be -4-α-Leg5Ac7Ala-4-β-d-ManNAlaA3OAc-3-α-d-GlcNAc-where Leg5Ac7Ala indicates 5-acetamido-7-alanylamido-3,5,7,9-tetradeoxy-d-glycero-d-galacto-non-2-ulopyranosonic acid and ManNAlaA3OAc 3-O-acetyl-2-alanylamido-2-deoxymannopyranuronic acid. The structure of the core with one repeating unit of the polysaccharide attached was also analyzed, and it was found that the O-chain polysaccharide is linked to the core via β-GlcpNAc, as opposite to α-GlcpNAc inside the O-chain.
