Reduced (Cu+) peptidylglycine alpha-hydroxylating monooxygenase (PHM) with bound nitrite

Template:ABSTRACT PUBMED 20958070

Function

[AMD_RAT] 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.
