EC 2.1.1.267 Flavonoid 3',5'-methyltransferase. [-]    

Reaction: (1) S-adenosyl-L-methionine + a 3'-hydroxyflavonoid = S-adenosyl-L- homocysteine + a 3'-methoxyflavonoid. (2) S-adenosyl-L-methionine + a 5'-hydroxy-3'-methoxyflavonoid = S-adenosyl-L-homocysteine + a 3',5'-dimethoxyflavonoid.

Comments: Isolated from Vitis vinifera (grape). Most active with delphinidin 3-glucoside but also acts on cyanidin 3-glucoside, cyanidin, myricetin, quercetin and quercetin 3-glucoside. The enzyme from Catharanthus roseus was most active with myricetin. Formerly Ec 2.1.1.149.
