12-oxophytodienoate reductase (OPRs) is an enzyme of the family of Old Yellow Enzymes (OYE). OPRs are grouped into two groups: OPRI and OPRII – the second group is the focus of this article as the function of the first group is unknown but is the subject of current research. The OPR enzyme utilizes the cofactor flavin mononucleotide (FMN) and catalyzses the following reaction in the jasmonic acid synthesis pathway: This reaction occurs in peroxisomes in plants.
