Catalyzes the synthesis of jasmonate-amino acid conjugates by adenylation. Catalyzes the conjugation of jasmonate (JA) to Ile when expressed in a heterologous system (E.Coli) (PubMed:21619871). Catalyzes in vitro the conjugation of jasmonate (JA) to Ile, Phe, Leu, Met, Val and Trp (PubMed:24033451). May catalyze the synthesis of indole-3-acetic acid (IAA)-amino acid conjugates, providing a mechanism for the plant to cope with the presence of excess auxin (By similarity). a jasmonate + an L-alpha-amino acid + ATP = a jasmonyl-L-amino acid + AMP + diphosphate + H(+) Expressed in green shoots and flowers. At low level by auxin. Induced by wounding (PubMed:21619871). Belongs to the IAA-amido conjugating enzyme family.
