Peptidyl-glycine alpha-amidating monooxygenase (PAM)

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's 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. .
