MetaCyc Reaction: 2.1.1.-

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 2.1.1.-

Enzymes and Genes:

Triticum aestivum : flavonoid O-methyltransferase Inferred from experiment : OMT2

Sub-reaction of:
2.1.1.169: 3 S-adenosyl-L-methionine + tricetin → 3 S-adenosyl-L-homocysteine + 3',4',5'-O-trimethyltricetin + 3 H+ ,
2.1.1.175: tricetin + 2 S-adenosyl-L-methionine → 3',5'-O-dimethyltricetin + 2 S-adenosyl-L-homocysteine + 2 H+

In Pathway: O -methylation of tricetin

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.
