Description
The enzymes from Oryza sativa (ROMT-15 and ROMT-17) catalyses the stepwise methylation of tricetin to its 3'-mono- and 3',5'-dimethyl ethers. In contrast with the wheat enzyme (EC 2.1.1.169, tricetin 3',4',5'-O-trimethyltransferase), tricetin dimethyl ether is not converted to its 3',4',5'-trimethylated ether derivative. The enzymes from Hordeum vulgare (HvOMT1) and from Zea mays (ZmOMT1) form the 3',5'-dimethyl derivative as the major product.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
ROMT-17; ROMT-15; HvOMT1; ZmOMT1
Reaction
2 S-adenosyl-L-methionine + tricetin = 2 S-adenosyl-L-homocysteine + 3',5'-O-dimethyltricetin (overall reaction); (1a) S-adenosyl-L-methionine + tricetin = S-adenosyl-L-homocysteine + 3'-O-methyltricetin; (1b) S-adenosyl-L-methionine + 3'-O-methyltricetin = S-adenosyl-L-homocysteine + 3',5'-O-dimethyltricetin
