In enzymology, an acyl-[acyl-carrier-protein]-UDP-N-acetylglucosamine O-acyltransferase (EC 2.3.1.129) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are (R)-3-hydroxytetradecanoyl-acyl-carrier-protein and UDP-N-acetylglucosamine, whereas its two products are acyl-carrier-protein and UDP-3-O-(3-hydroxytetradecanoyl)-N-acetylglucosamine.
This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is (R)-3-hydroxytetradecanoyl-[acyl-carrier-protein]:UDP-N-acetylglucosamine 3-O-(3-hydroxytetradecanoyl)transferase. Other names in common use include UDP-N-acetylglucosamine acyltransferase and uridine diphosphoacetylglucosamine acyltransferase. This enzyme participates in lipopolysaccharide biosynthesis.
