Catalyzes the synthesis of jasmonate-amino acid conjugates by adenylation (PubMed:17085687, PubMed:17273867). Catalyzes the conjugation of jasmonate (JA) to Ile, Leu and Val (PubMed:17273867). Catalyzes the conjugation of jasmonate (JA) to Ile to mediate defense signaling and resistance to the herbivore Manduca sexta caterpillars (PubMed:17085687). a jasmonate + an L-alpha-amino acid + ATP = a jasmonyl-L-amino acid + AMP + diphosphate + H(+) Induced by wounding (PubMed:17085687, PubMed:17273867). Induced by oral secretion of the herbivore Manduca sexta caterpillars (PubMed:17273867). Induced by treatment with JA-Ile (PubMed:17085687). Belongs to the IAA-amido conjugating enzyme family.
