Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
Specific Species Reactivity: Arabidopsis thaliana
JAR1 encodes a soluble, cytosolic GH3-family acyl acid-amido synthetase of the firefly luciferase-like adenylate-forming enzyme superfamily that functions in jasmonate hormone bioactivation in plants. The gene produces a protein of roughly mid-60 kDa size that contains the conserved GH3/adenylate-forming catalytic architecture used to activate carboxylate substrates with ATP (via an acyl-adenylate intermediate) prior to amide bond formation with amino acids. Biochemically, JAR1 preferentially conjugates jasmonic acid to L-isoleucine to generate jasmonoyl-L-isoleucine (JA-Ile), a principal bioactive jasmonate that drives downstream signaling by promoting COI1-dependent perception and subsequent turnover of JAZ transcriptional repressors, thereby enabling rapid transcriptional reprogramming during wounding and defense responses. Genetic disruption of JAR1 reduces JA-Ile accumulation and impairs multiple jasmonate-dependent phenotypes, consistent with a central role in converting the jasmonate precursor pool into an active signal that coordinates stress adaptation and aspects of development.
