Common NameUndecaprenyl-N-acetyl-alpha-D-glucosaminyl-pyrophosphate
DescriptionUndecaprenyl-N-acetyl-alpha-D-glucosaminyl-pyrophosphate or C5PP GlcNAc is involved in ECA biosynthesis. It is a substrate for Undecaprenyl-phosphate alpha-N-acetylglucosaminyl 1-phosphate transferase. This enzyme catalyzes the transfer of the GlcNAc-1-phosphate moiety from UDP-GlcNAc onto the carrier lipid undecaprenyl phosphate (C55-P), yielding GlcNAc-pyrophosphoryl-undecaprenyl (GlcNAc-PP-C55). It is the first lipid-linked intermediate involved in enterobacterial common antigen (ECA) synthesis and an acceptor for the addition of subsequent sugars to complete the biosynthesis of O-antigen (PMID 1730666 ). GlcNAc-pyrophosphorylundecaprenol functions as the acceptor of mannose residues for the in vivo synthesis of O8 side chains in E. coli.(PMID 7514591 ). Enterobacterial common antigen (ECA) is an outer membrane glycolipid common to all members of Enterobacteriaceae. The carbohydrate portion consists of N-acetyl-glucosamine, N-acetyl-D-mannosaminuronic acid and 4-acetamido-4,6-dideoxy-D-galactose. These amino sugars form trisaccharide repeat units which are part of linear heteropolysaccharide chains.
