12-Oxophytodienoate reductase 3 (OPR3), one of the enzymes involved in the biosynthesis of the plant hormone jasmonic acid (JA), catalyzes the reduction of the cyclopentenone ring of (9 S ,13 S )-12-oxophytodienoate [(9 S ,13 S )-OPDA]. However, there has been no structural information about the interaction between OPRs and the physiologically relevant (9 S ,13 S )-OPDA. Here we report the crystal structure of Arabidopsis thaliana OPR3 in complex with 8- iso prostaglandin A1 (8- iso PGA 1 ) which has the same stereochemistry in the cyclopentenone ring as in the physiologically relevant 9 S ,13 S -OPDA. This structure reveals a new binding mode for substrate that likely contributes to the relaxed stereospecificity observed for AtOPR3.
