CC -!- FUNCTION: Catalyzes the post-translational formation of 4-
CC hydroxyproline in -Xaa-Pro-Gly- sequences in proline-rich peptide
CC sequences of plant glycoproteins and other proteins. Hydroxyprolines
CC are important constituent of many plant cell wall glycoproteins such as
CC extensins, hydroxyproline-rich glycoproteins, lectins and
CC arabinogalactan proteins. {ECO:0000250|UniProtKB:Q9ZW86}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2-oxoglutarate + L-prolyl-[collagen] + O2 = CO2 + succinate +
CC trans-4-hydroxy-L-prolyl-[collagen]; Xref=Rhea:RHEA:18945, Rhea:RHEA-
CC COMP:11676, Rhea:RHEA-COMP:11680, ChEBI:CHEBI:15379,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:16810, ChEBI:CHEBI:30031,
CC ChEBI:CHEBI:50342, ChEBI:CHEBI:61965; EC=1.14.11.2;
CC Evidence={ECO:0000250|UniProtKB:Q9ZW86};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00805};
CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00805};
CC -!- COFACTOR:
CC Name=L-ascorbate; Xref=ChEBI:CHEBI:38290;
CC Evidence={ECO:0000250|UniProtKB:Q86KR9};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q24JN5}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q24JN5}.
CC -!- SIMILARITY: Belongs to the P4HA family. {ECO:0000305}.
