flavonoid 3',5'-methyltransferase
S-adenosyl-L-methionine + 3'-O-methylmyricetin = S-adenosyl-L-homocysteine + 3',5'-di-O-methylmyricetin
: Is a subreaction of The enzyme from TAX-4058 (Madagascar periwinkle) is unusual as it carries out two methylations of the same substrate. Also catalyses the methylation of dihydromyricetin. The other reaction is RXN-8451
