EC 2.1.1.169

Names

Accepted name:
tricetin 3',4',5'-O-trimethyltransferase
Other names:
FOMT
TaOMT1

TaOMT2
Systematic name:
S-adenosyl-L-methionine:tricetin 3',4',5'-O-trimethyltransferase

Reaction

Comments:

The enzyme from Triticum aestivum catalyses the sequential O-methylation of tricetin via 3'-O-methyltricetin, 3',5'-O-methyltricetin to 3',4',5'-O-trimethyltricetin [2].
