IUBMB Comments

Two jasmonoyl-L-amino acid synthetases have been described from Nicotiana attenuata and one from Arabidopsis thaliana . The N. attenuata enzymes generate jasmonoyl-L-isoleucine, jasmonoyl-L-leucine, and jasmonoyl-L-valine. The enzyme from A. thaliana could catalyse the addition of many different amino acids to jasmonate in vitro [1,4,5]. While the abundant form of jasmonate in plants is (–)-jasmonate, the active form of jasmonoyl-L-isoleucine is (+)-7-iso-jasmonoyl-L-isoleucine.
