Peptidyl-glycine alpha-amidating monooxygenase

Gene

Pam

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Bifunctional enzyme that catalyzes 2 sequential steps in C-terminal alpha-amidation of peptides. The monooxygenase part produces an unstable peptidyl(2-hydroxyglycine) intermediate that is dismutated to glyoxylate and the corresponding desglycine peptide amide by the lyase part. C-terminal amidation of peptides such as neuropeptides is essential for full biological activity (By similarity).By similarity

Catalytic activityi

Peptidylglycine + ascorbate + O2 = peptidyl(2-hydroxyglycine) + dehydroascorbate + H2O.
Peptidylamidoglycolate = peptidyl amide + glyoxylate.

Cofactori

Protein has several cofactor binding sites:
  • Zn2+By similarityNote: Zn2+ is required for the lyase reaction.By similarity
  • Cu2+By similarityNote: Binds 2 copper ions per subunit for the monoxygenase reaction.By similarity
