Jasmonate O-methyltransferase

In enzymology, a jasmonate O-methyltransferase (EC 2.1.1.141) is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + jasmonate ${\displaystyle \rightleftharpoons }$ S-adenosyl-L-homocysteine + methyl jasmonate

Thus, the two substrates of this enzyme are S-adenosyl methionine and jasmonate, whereas its two products are S-adenosylhomocysteine and methyl jasmonate.

This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:jasmonate O-methyltransferase. This enzyme is also called jasmonic acid carboxyl methyltransferase.
