1.14.17.3 | physiological function | PAM is a bifunctional enzyme, its copper-dependent peptidylglycine alpha-hydroxylating monooxygenase, PHM, domain converts peptidylglycine substrates to peptidyl-alpha-hydroxyglycine intermediates that are subsequently converted into amidated products plus glyoxylate by the zinc-dependent peptidyl-alpha-hydroxyglycine alpha-amidating lyase (PAL) domain. The reaction catalyzed by PHM results in the stereospecific incorporation of one atom of molecular oxygen into the substrate in a reaction that involves two single electron transfer steps. PAM-mediated C-terminal amidation occurs across a range of biologically active endocrine and nervous system peptides and in many cases has been shown to be required for normal biological activity in vivo. Peptidylglycine alpha-amidating monooxygenase (PAM) is solely responsible for catalysis of amidation, a biologically important posttranslational modification. Peptide substrate amidation is strikingly sensitive to the exposure of cells to moderate hypoxia, physiological effects of hypoxia may be PAM-dependent. Because PAM-dependent amidation is irreversible, bi-directional responses that rapidly upregulate and downregulate levels of amidation can only be observed on rapidly turned-over PAM substrates | Homo sapiens |
