additional information | EC 1.14.17.3 is often called peptidylglycine alpha-amidating monooxygenase (PAM) and the alpha-amidated product is mentioned as the product of the reaction, but the alpha-amidation of glycine-extended peptides is a two-step process catalyzed by 2 enzymes: 1. EC 1.14.17.3: production of peptidyl(2-hydroxyglycine) by a copper, molecular oxygen and ascorbate-dependent peptidyl-glycine alpha-hydroxylating monooxygenase (PMH) and 2. conversion of the peptidyl-alpha-hydroxyglycine derivative into an alpha-amidated product at physiological pH by peptidyl-alpha-hydroxyglycine alpha-amidating lyase | Rattus norvegicus | ? | - |
