) These enzymes act on carboxylic esters (EC: 3.1.1.-). The catalytic apparatus involves three residues (catalytic triad): a serine, a glutamate or aspartate and a histidine.These catalytic residues are responsible for the nucleophilic attack on the carbonyl carbon atom of the ester bond. In contrast with other alpha/beta hydrolase fold family members, p-nitrobenzyl esterase and acetylcholine esterase have a Glu instead of Asp at the active site carboxylate. Length = 493

Among the different types are those which act on carboxylic esters (3.1.1 from EC). Carboxyl-esterases have been classified into three categories (A, B and C) on the basis of differential patterns of inhibition by organophosphates. The sequence of a number of type-B carboxylesterases indicates [, , ] that the majority are evolutionary related. As is the case for lipases and serine proteases, the catalytic apparatus of esterases involves three residues (catalytic triad): a serine, a glutamate or aspartate and a histidine.; PDB: 3B3Q_A 1CLE_B 1GQS_A 2VJD_A 1HBJ_A 2C5G_A 1U65_A 2WG1_A 1FSS_A 3M3D_A ....
