ID 1.14.17.3 DE peptidylglycine monooxygenase. AN PAM. AN peptidyl alpha-amidating enzyme. AN peptidylglycine 2-hydroxylase. AN peptidylglycine alpha-amidating monooxygenase. CA a [peptide]-C-terminal glycine + 2 L-ascorbate + O2 = a [peptide]-C- CA terminal (2S)-2-hydroxyglycine + H2O + 2 monodehydro-L-ascorbate radical. CC -!- A copper protein. CC -!- The enzyme binds two copper ions with distinct roles during CC catalysis. CC -!- Peptidylglycines with a neutral amino acid residue in the penultimate CC position are the best substrates for the enzyme. CC -!- The product is unstable and dismutates to glyoxylate and the CC corresponding desglycine peptide amide, a reaction catalyzed by CC EC 4.3.2.5. CC -!- In mammals, the two activities are part of a bifunctional protein. CC -!- Involved in the final step of biosynthesis of alpha-melanotropin and CC related biologically active peptides.
