EC 1.14.11.7

Names

Accepted name:
procollagen-proline 3-dioxygenase
Other names:
proline,2-oxoglutarate 3-dioxygenase
prolyl 3-hydroxylase
prolyl-4-hydroxyprolyl-glycyl-peptide,2-oxoglutarate:oxygen oxidoreductase, 3-hydroxylating
protocollagen proline 3-hydroxylase
procollagen-proline,2-oxoglutarate 3-dioxygenase
Systematic name:
[procollagen]-L-proline,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating)

Reaction

Cofactors

Comments:

Requires Fe2+ and ascorbate. The enzyme forms a complex with protein disulfide isomerase, and is located in the endoplasmic reticulum. It modifies proline residues within the procollagen peptide of certain collagen types. The modification is essential for proper collagen triple helix formation.
