Glossary: tetradecanoyl = myristoyl

Other name(s): UDP-N-acetylglucosamine acyltransferase; uridine diphosphoacetylglucosamine acyltransferase

Systematic name: (R)-3-hydroxytetradecanoyl-[acyl-carrier protein]:UDP-N-acetylglucosamine 3-O-(3-hydroxytetradecanoyl)transferase

Comments: Involved with EC (lipid-A-disaccharide synthase) and EC (tetraacyldisaccharide 4'-kinase) in the biosynthesis of the phosphorylated glycolipid, Lipid A, in the outer membrane of Escherichia coli.
