Substrates and Products (Substrate)

Substrates Comment Substrates Organism Products Comment (Products) Rev. Reac.
3 S-adenosyl-L-methionine + tricetin the enzyme catalyzes three sequential O-methylations, forming 3'-O-methyltricetin, 3',5'-dimethyltricetin and 3',4',5'-O-trimethyltricetin. Tricetin is the preferred substrate. Also catalyzes the methylation of 5-hydroxyferulic acid, luteolin, quercetin, eriodyctiol, quercetagetin, taxifolin, gossypetin and myricetin. TaOMT2 is a flavonoid, B-ring-specific O-methyltransferase with a preference for flavones > dihydroflavones > flavonols that possess at least two, B-ring hydroxyl groups Triticum aestivum 3 S-adenosyl-L-homocysteine + 3',4',5'-O-trimethyltricetin

S-adenosyl-L-methionine + 3',5'-O-dimethyltricetin the enzyme catalyzes three sequential O-methylations, forming 3'-O-methyltricetin, 3',5'-dimethyltricetin and 3',4',5'-O-trimethyltricetin. Tricetin is the preferred substrate Triticum aestivum S-adenosyl-L-homocysteine + 3',4',5'-O-trimethyltricetin
