  3.5.1.127 | physiological function |
amidohydrolases IAR3 and ILL6 define a second pathway for jasmonoyl-L-isoleucine turnover during the wound response in Arabidopsis thaliana leaves. The two enzymes cleave the jasmonoyl-L-isoleucine signal, but act also on the tuberonic acid-isoleucine conjugate. The abundant accumulation of tuberonic acid (12-hydroxyjasmonic acid) after wounding originates partly through a sequential pathway involving conjugation of jasmopnic acid to isoleucine, oxidation of the jasmonoyl-L-isoleucine conjugate, and cleavage under the action of the amidohydrolases |

aminohydrolases Ill6 and Iar3 are asmonoyl-isoleucine amidohydrolases. Increased turnover of asmonoyl-isoleucine in the ILL6- and IAR3-overexpressing plants creates symptoms of jasmonoyl-isoleucine deficiency |

| 3.5.1.127 | physiological function |
aminohydrolases Ill6 and Iar3 are asmonoyl-isoleucine amidohydrolases. Increased turnover of asmonoyl-isoleucine in the ILL6- and IAR3-overexpressing plants creates symptoms of jasmonoyl-isoleucine deficiency. Ill6 overexpression renders plants highly resistant to exogenous indole-3-acetic acid conjugates |

| 3.5.1.127 | physiological function |
jasmonoyl-L-isoleucine levels are increased in wounded leaves of a Cyp94b3 jasmonoyl-L-isoleucine oxidase mutant but not a Ill6 single mutant. Jasmonoyl-L-isoleucine levels in the Cyp94b3/Ill6 double mutant are significantly greater than that in the Cyp94b3 single mutant consistent with the collaborative action of the oxidative and the hydrolytic pathways in jasmonoyl-L-isoleucine turnover |

| 3.5.1.127 | physiological function |
upon silencing of the JIH1 gene by RNA interference, jasmonoyl-L-isoleucine levels increase dramatically after simulated herbivory , compared with wild-type plants. When specialist (Manduca sexta) or generalist (Spodoptera littoralis) herbivores feed on silenced plants they gain significantly less mass compared with those feeding on wild-type plants. The poor larval performance is strongly correlated with the higher accumulation of several jasmonoyl-L-isoleucine-dependent direct defense metabolites in silenced plants. In the field, these plants attract substantially more Geocoris predators to the experimentally attached Manduca sexta eggs on their leaves, compared with empty vector plants |
