IUBMB Enzyme Nomenclature


Accepted name: jasmonate O-methyltransferase

Reaction: S-adenosyl-L-methionine + jasmonate = S-adenosyl-L-homocysteine + methyl jasmonate

Glossary entries:
jasmonic acid = {(1R,2R)-3-oxo-2-[(Z)pent-2-enyl]cyclopent-2-enyl}acetic acid.

Other name(s): jasmonic acid carboxyl methyltransferase

Systematic name: S-adenosyl-L-methionine:jasmonate O-methyltransferase

Comments: 9,10-Dihydrojasmonic acid is a poor substrate for the enzyme. The enzyme does not convert 12-oxo-phytodienoic acid (a precursor of jasmonic acid), salicylic acid, benzoic acid, linolenic acid or cinnamic acid into their corresponding methyl esters. Enzyme activity is inhibited by the presence of divalent cations, e.g., Ca2+, Cu2+, Mg2+ and Zn2+.
