. "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., Ca(2+), Cu(2+), Mg(2+) and Zn(2+)." . . . "Jasmonate O-methyltransferase" . "Jasmonic acid carboxyl methyltransferase" .
