2 S-adenosyl-L-methionine + myricetin
the enzyme also catalyzes the methylation of luteolin, tricetin and caffeoyl-CoA. ROMT-15 exhibits similar kcat/Km values for the four substrates. ROMT-15 can not utilize naringenin, apigenin, or kaempferol. The 2,3-double bond and the O-dihydroxyl group are both required for catalytic activity
2 S-adenosyl-L-homocysteine + syringetin
syringetin is the 3',5'-dimethyl ether of myricetin

2 S-adenosyl-L-methionine + myricetin
the enzyme also catalyzes the methylation of luteolin, tricetin and caffeoyl-CoA. ROMT-17 prefers tricetin. ROMT-15 can not utilize naringenin, apigenin, or kaempferol. The 2,3-double bond and the O-dihydroxyl group are both required for catalytic activity
2 S-adenosyl-L-homocysteine + syringetin
syringetin is the 3',5'-dimethyl ether of myricetin
