Protein attributes

Sequence length	523 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the 3'5'-hydroxylation of naringenin and eriodictyol to form 5,7,3,'4',5'-pentahydroxyflavanone and 3',5'-hydroxylation of dihydrokaempferol and dihydroquercetin to form dihydromyricetin By similarity.
Catalytic activity	A flavanone + NADPH + O2 = a 3'-hydroxyflavanone + NADP+ + H2O. A 3'-hydroxyflavanone + NADPH + O2 = a 3',5'-dihydroxyflavanone + NADP+ + H2O.
Cofactor	Heme group By similarity.
Pathway	Pigment biosynthesis; anthocyanin biosynthesis.
Sequence similarities	Belongs to the cytochrome P450 family.
