Biol. Chem. 280:14645-14655(2005). CC -!- FUNCTION: Catalyzes the post-translational formation of 4- CC hydroxyproline. Probably hydroxylates skp1 on Pro-143. CC -!- CATALYTIC ACTIVITY: Peptide L-proline + 2-oxoglutarate + O(2) = CC Peptide 4-hydroxy-L-proline + succinate + CO(2). CC -!- COFACTOR: Binds 1 Fe(2+) ion per subunit (By similarity). CC -!- COFACTOR: Ascorbate. CC -!- ENZYME REGULATION: Inhibited by the prolyl-hydroxylase inhibitors CC alpha,alpha'-dipyridyl and ethyl 3,4-dihydroxybenzoate. CC -!- SUBUNIT: Heterotetramer of two alpha-1 chains and two beta chains CC (the beta chain is the multi-functional PDI) (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the P4HA family. CC -!- SIMILARITY: Contains 1 PKHD (prolyl/lysyl hydroxylase) domain.
