Enzyme Information
| 1.14.11.2 |
Procollagen-proline 4-dioxygenase.
based on mapping to UniProt O15460
L-proline-[procollagen] + 2-oxoglutarate + O(2) = trans-4-hydroxy-L- proline-[procollagen] + succinate + CO(2).
-!- The enzyme, which is located within the lumen of the endoplasmic reticulum, catalyzes the 4-hydroxylation of prolines in -X-Pro-Gly- sequences. -!- The 4-hydroxyproline residues are essential for the formation of the collagen triple helix. -!- The enzyme forms a complex with protein disulfide isomerase and acts not only on procollagen but also on more than 15 other proteins that have collagen-like domains.
