ID 2.1.1.141 DE jasmonate O-methyltransferase. AN jasmonic acid carboxyl methyltransferase. CA jasmonate + S-adenosyl-L-methionine = methyl (-)-jasmonate + S-adenosyl- CA L-homocysteine. CC -!- 9,10-Dihydrojasmonic acid is a poor substrate for the enzyme. CC -!- The enzyme does not convert 12-oxo-phytodienoic acid (a precursor of CC jasmonic acid), salicylic acid, benzoic acid, linolenic acid or CC cinnamic acid into their corresponding methyl esters. CC -!- Enzyme activity is inhibited by the presence of divalent cations, CC e.g., Ca(2+), Cu(2+), Mg(2+) and Zn(2+).
