== Function ==
[https://www.uniprot.org/uniprot/OPR3_SOLLC OPR3_SOLLC] Specifically cleaves olefinic bonds in cyclic enones. Involved in the biosynthesis of jasmonic acid (JA) and perhaps in biosynthesis or metabolism of other oxylipin signaling moleclules. It is required for the spatial and temporal regulation of JA levels during dehiscence of anthers, promoting the stomium degeneration program (By similarity). 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.
