CC   -!- FUNCTION: Catalyzes the 3'5'-hydroxylation of naringenin and
CC       eriodictyol to form 5,7,3,'4',5'-pentahydroxyflavanone and 3',5'-
CC       hydroxylation of dihydrokaempferol and dihydroquercetin to form
CC       dihydromyricetin.
CC   -!- CATALYTIC ACTIVITY: A flavanone + NADPH + O(2) = a 3'-
CC       hydroxyflavanone + NADP(+) + H(2)O.
CC   -!- CATALYTIC ACTIVITY: A 3'-hydroxyflavanone + NADPH + O(2) = a
CC       3',5'-dihydroxyflavanone + NADP(+) + H(2)O.
CC   -!- COFACTOR: Heme group (By similarity).
CC   -!- PATHWAY: Pigment biosynthesis; anthocyanin biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Microsome (Potential). Endoplasmic reticulum
CC       (By similarity).
CC   -!- TISSUE SPECIFICITY: Flowers.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family.
