aryldialkylphosphatase  M-CSA #159

Phosphotriesterase (PTE) contains a binuclear zinc catalytic site, a structural motif characteristic of the amidohydrolase superfamily. The enzyme acts to hydrolyse phosphoesters via nucleophilic attack at the substrate PO bond from the bridging hydroxide ligand.
