ENZYME entry: EC 2.1.1.175

PURL: https://purl.expasy.org/enzyme/EC/2.1.1.175
Accepted Name
tricin synthase
Reaction catalysed
tricetin + 2 S-adenosyl-L-methionine = 3',5'-di-O-methyltricetin + 2 S-adenosyl-L-homocysteine + 2 H(+)
Comment(s)
  • The enzymes from Oryza sativa (ROMT-15 and ROMT-17) catalyzes the stepwise methylation of tricetin to its 3'-mono- and 3',5'-dimethyl ethers.
  • In contrast with the wheat enzyme (EC 2.1.1.167, 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.
