CC -!- FUNCTION: Catalyzes the 3'-hydroxylation of the flavonoid B-ring to the
CC 3',4'-hydroxylated state. Convert naringenin to eriodictyol and
CC dihydrokaempferol to dihydroquercetin.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 3'-unsubstituted flavone + O2 + reduced [NADPH--hemoprotein
CC reductase] = a 3'-hydroxyflavone + H(+) + H2O + oxidized [NADPH--
CC hemoprotein reductase]; Xref=Rhea:RHEA:16337, Rhea:RHEA-COMP:11964,
CC Rhea:RHEA-COMP:11965, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15379, ChEBI:CHEBI:27741, ChEBI:CHEBI:57618,
CC ChEBI:CHEBI:58210, ChEBI:CHEBI:138726; EC=1.14.14.82;
CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC -!- PATHWAY: Secondary metabolite biosynthesis; flavonoid biosynthesis.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000305};
CC Single-pass type III membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: High expression in siliques and to a lower extent
CC in stems, flowers and senescing leaves.
CC -!- INDUCTION: By UV light treatment.
CC -!- MISCELLANEOUS: May act as a membrane anchor for localization of other,
CC soluble, flavonoid enzymes to the endoplasmic reticulum.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
