Common NameUndecaprenyl-diphospho N-acetylglucosamine-N-acetylmannosaminuronate-N-acetamido-4,6-dideoxy-D-galactose
DescriptionUndecaprenyl-diphospho N-acetylglucosamine-N-acetylmannosaminuronate-N-acetamido-4,6-dideoxy-D-galactose is an intermediate in enterobacterial common antigen (ECA) synthesis. It is a substrate for 4-alpha-L-fucosyltransferase (wecF) This enzyme catalyzes the synthesis of Und-PP-GlcNAc-ManNAcA-Fuc4NAc (Lipid III), the third lipid-linked intermediate involved in ECA synthesis. Enterobacterial common antigen (ECA) is an outer membrane glycolipid similar to LPS that is 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.
