spinqualitylabelsall models E. coli UDP-N-acetylglucosamine acyltransferase complex with UDP-Glc-NAC (PDB code 2jf3) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function UDP-N-acetylglucosamine acyltransferase (LpxA) initiates lipid A biosynthesis. It catalyzes the transfer of 3-hydroxymyristic acid from acyl carrier protein to the 3'-hydroxyl group of UDP-GlcNAc[1]. Structural highlights The of LpxA interacts with the substrate UDP moiety and the Glc-NAc moiety. It contains a where the His acts as a general base and Asp helps to orient the His for participation in the catalysis[2].
