2.1.1.141 jasmonate O-methyltransferaseIUBMB 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+.

expression of the gene is induced both locally and systematically by wounding or methyl jasmonate treatement. The jasmonic acid carboxyl methyltransferase is a key enzyme for jasmonate-regulated plant responses. Activation of JMT expression leads to production of methyl jasmonate that could act as an intracellular regulator, a diffusible intercellular transducer, and an airborne signal mediating intra- and interplant communications

overexpression of enzyme in the Glycine max seeds results in decreased amounts of tryptophan, palmitic acid, linolenic acid, and stachyose, but increased levels of gadoleic acid and genistein. In particular, seeds contain 120.0-130.5% more genistein and 60.5-82.1% less stachyose than the wild type
