comments
This enzyme is homologous to Palmitoyl-protein thioesterase (S00350 in EzCatDB) with a similar active site. This enzyme must catalyze a similar hydrolysis reaction of thioester group to that by the homologous enzyme.
According to the literature [1], this enzyme is involved in polyketide synthases (PKSs) and non-ribosomal peptide synthetases (NRPSs). This enzyme catalyzes thioester cleavage, which releases the assembled polyketide/peptide from phosphopantetheine arms of acyl/peptidyl carrier protein (ACP/PCP; see U00001 in EzCatDB) as the final reaction step (see [1]).
