Template:Infobox enzyme Tricin synthase (Template:EC number, ROMT-17, ROMT-15, HvOMT1, ZmOMT1) is an enzyme with systematic name S-adenosyl-L-methionine:tricetin 3',5'-O-dimethyltransferase.[1][2] This enzyme catalyses the following chemical 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
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.
