2.4.1.182 additional information involved in the biosynthetic pathway leading to 3-aminoglucosamine analogues of lipid A, responsible for cytotoxic effect on the host Acanthamoeba castellanii 2.4.1.182 additional information formation of lipid A disaccharide from UDP-GlcNAc and lipid X, i.e. 2,3-diacylglucosamine 1-phosphate, releasing UDP. Lipid X, i.e. 2,3-diacylglucosamine 1-phosphate, bears two R-3-hydroxymyristoyl chains in Arabidopsis thaliana and is a key precursor of lipid A. No other lipid X molecular species are detected 2.4.1.182 additional information LpxB combines lipid X with the preceding lipid metabolite, UDP-2,3-bis(beta-hydroxymyristoyl)-D-glucosamine, to form lipid A disaccharide 2.4.1.182 UDP-2,3-bis((R)-3-hydroxytetradecanoyl)-alpha-D-glucosamine + 2,3-bis((R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-phosphate - 2.4.1.182 UDP-2,3-bis((R)-3-hydroxytetradecanoyl)-alpha-D-glucosamine + 2,3-bis((R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-phosphate involved with EC 2.3.1.129 and EC 2.7.1.130 in the biosynthesis of the phosphorylated glycolipid, Lipid A, in the outer membrane of E. coli and other gram-negative bacteria 2.4.1.182 UDP-2,3-bis((R)-3-hydroxytetradecanoyl)-alpha-D-glucosamine + 2,3-bis((R)-3-hydroxytetradecanoyl)-alpha-D-glucosaminyl 1-phosphate involved in lipid A biosynthesis 2.4.1.182 UDP-2,3-bis(3-hydroxytetradecanoyl)glucosamine + 2,3-bis(3-hydroxytetradecanoyl)-beta-D-glucosaminyl 1-phosphate - 2.4.1.182 UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-glucosamine + 2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-alpha-D-glucosaminyl 1-phosphate -
