Common NameUDP-2,3-diacetamido-2,3-dideoxy-alpha-D-glucuronic acid
DescriptionUDP-2,3-diacetamido-2,3-dideoxy-alpha-D-glucuronic acid is a nucleotide sugar that belongs to the class of uridine diphosphate (UDP) sugars. Its chemical structure features a uridine moiety linked to a sugar derivative, specifically a modified form of glucuronic acid that includes two acetamido groups and lacks hydroxyl groups at the 2 and 3 positions. This compound is involved in the biosynthetic pathway of polysaccharides, particularly in the synthesis of bacterial exopolysaccharides. The biosynthesis of UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-glucuronic acid is proposed to involve five enzymatic steps, beginning with UDP-alpha-D-GlcNAc (UDP-N-acetyl-alpha-D-glucosamine) and progressing through four intermediate transformations to yield UDP-alpha-D-GlcNAc3NAcA. This intermediate is then epimerized by the action of specific enzymes, such as WbpI and WlbD, which have been characterized as UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-glucuronic acid 2-epimerases (PMID:17346239 ). These enzymatic processes highlight the compound's role in microbial metabolism and its potential implications in pathogenicity.
