Accepted name: jasmonate O-methyltransferase
Reaction: S-adenosyl-L-methionine + jasmonate = S-adenosyl-L-homocysteine + methyl jasmonate
Glossary: 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+.
