Oxidized (Cu2+) peptidylglycine alpha-hydroxylating monooxygenase (PHM) with bound azide obtained by soaking (100mM NaN3)
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.
About this Structure
