12-oxophytodienoate reductase 3

UniProtKB accession:  Q9FUP0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Specifically cleaves olefinic bonds in cyclic enones (PubMed:11094980). Involved in the biosynthesis of jasmonic acid (JA) and perhaps in biosynthesis or metabolism of other oxylipin signaling moleclules (PubMed:10872231, PubMed:10973494, PubMed:29291349). Required for the spatial and temporal regulation of JA levels during dehiscence of anthers, promoting the stomium degeneration program (PubMed:10899973, PubMed:10973494). In vitro, reduces 9S,13S-12-oxophytodienoic acid (9S,13S-OPDA) and 9R,13R-OPDA to 9S,13S-OPC-8:0 and 9R,13R-OPC-8:0, respectively (PubMed:10872231). Can detoxify the explosive 2,4,6-trinitrotoluene (TNT) in vitro by catalyzing its nitroreduction to form hydroxylamino-dinitrotoluene (HADNT) (PubMed:19605548).
