| - | '''12-oxophytodienoate reductase''' (OPR) | + | '''12-oxophytodienoate reductase''' (OPR) catalyzes the conversion of 12-oxophytodienoate to 3-oxo-pentenyl-cyclopentane octanoate. The expression of OPR is induced by stimuli like touch, wind, wounding, UV light and detergent. OPR uses the cofactor flavin mononucleotide (FMN) which is reduced by NADPH. OPR exhibits self inhibition by dimerization. Three isozymes of OPR are known – OPR1, OPR2, OPR3.<br /> |
