EC 2.1.1.267

Names

Accepted name:
flavonoid 3',5'-methyltransferase
Other names:
AOMT
CrOMT2
Systematic name:
S-adenosyl-L-methionine:flavonoid 3'-O-methyltransferase

Reactions

Comments:

Isolated from Vitis vinifera (grape) [2]. 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 [1].
