Procollagen Proline Dioxygenase
- mixed-function oxygenase that catalyzes hydroxylation prolyl-glycyl-containing-peptide, usually in protocollagen, hydroxyprolylglycyl-peptide. The enzyme utilizes molecular oxygen with a concomitant oxidative decarboxylation of 2-oxoglutarate to succinate. EC 1.14.11.2.
