Abstract
The sequence and analysis of the capsular polysaccharide biosynthesis locus, PS B2, of Bacteroides fragilis 638R are described, and the sequence is compared with that of the PS B1 biosynthesis locus of B. fragilis NCTC 9343. Two genes of the region, wcgD and wcgC, are shown by complementation to encode a UDP-N-acetylglucosamine 2-epimerase and a UDP-N-acetylmannosamine dehydrogenase, respectively.
