MetaCyc Enzyme: jasmonoyl-amino acid synthetase

Gene: JAR4 Accession Number: G-11278 (MetaCyc)

Synonyms: JA-amino synthetase, JA-amido conjugate synthetase, jasmonic acid:amino acid synthetase, jasmonate:amino acid synthetase, jasmonate:amino acid ligase (AMP-forming), jasmonyl-amino acid synthetase

Species: Nicotiana attenuata

Summary:
JAR4 is a jasmonyl-amino acid synthetase that is up-regulated, at the transcriptional level, in response to wounding, or wounding and treatment with the oral secretions of the herbivorous tobacco hornworm (Manduca sexta) [Wang07b]. Plants with reduced levels of JAR4 transcripts produce lower amounts of JA-isoleucine [Wang07b, Kang06], JA-leucine, and JA-valine [Wang07b], suggesting that this enzyme is involved in the production of those compounds in vivo.
