the active site of PatA comprises a catalytic triad consisting of the acceptor O6 atom of Manp, the imidazole ring of His126, and the carboxylate group of Glu200. In the proposed reaction mechanism, His126 acts initially as a general base to deprotonate the acceptor hydroxyl group, facilitating the nucleophilic attack on the thioester bond of palmitoyl-CoA. The carboxylic group of Glu200 contributes to the correct positioning of the imidazole ring of His126 and is involved in a charge relay system that increases the nucleophilicity of the acceptor Manp hydroxyl and modulates the pKa of His126 to act as a base in the first step and as an acid in the second step, providing protonic assistance to the departing CoA leaving group |
