LITERATURE
evolution
residue Val309 determines substrate specificity for tricetin and may define the evolutionary differences between the two closely related proteins, COMT and flavone OMT
metabolism
TaOMT2 catalyzes the sequential methylation of the flavone, tricetin, to its 3'-methyl-, 3',5'-dimethyl-, and 3',4',5'-trimethyl ether derivatives. Tricin, a potential multifunctional nutraceutical, is the major enzyme reaction product
