P4Ha_N

P4Ha_N
PFAM accession number:PF08336
Interpro abstract (IPR013547):

The members found in this entry are eukaryotic proteins, and include all three isoforms of the prolyl 4-hydroxylase alpha subunit. This enzyme (EC 1.14.11.2) is important in the post-translational modification of collagen, as it catalyses the formation of 4-hydroxyproline. In vertebrates, the complete enzyme is an alpha2-beta2 tetramer; the beta-subunit is identical to protein disulphide isomerase [(PUBMED:7753822), (PUBMED:14500733), (PUBMED:2552442), (PUBMED:11850189)]. The function of the N-terminal region featured in this family does not seem to be known.

GO process:oxidation-reduction process (GO:0055114)
GO component:endoplasmic reticulum (GO:0005783)
GO function:oxidoreductase activity, acting on single donors with incorporation of molecular oxygen, incorporation of two atoms of oxygen (GO:0016702), procollagen-proline 4-dioxygenase activity (GO:0004656)
