reaction mechanism, acylation occurs via nucleophilic attack of deprotonated UDP-GlcNAc on the acyl donor in a general base-catalyzed mechanism involving a catalytic dyad of His125 and Asp126, His125, the general base, interacts with the 3'-hydroxyl group of UDP-GlcNAc to generate the nucleophile, the Asp126 side-chain accepts a hydrogen bond from His125 and helps orient the general base to participate in catalysis |
