1.3.1.42 | at 2.0 A resolution, determination of the crystal structures of OPR3 in complex with the ligand p-hydroxybenzaldehyde, structural comparison with the OPR1:(9R,13R)-12-oxophytodienoate complex and further biochemical and mutational analyses reveals that 2 active-site residues, Phe74 and His244 in OPR3 are critical for substrate filtering | Solanum lycopersicum |
1.3.1.42 | OPR1:p-hydroxybenzaldehyde complex at 2.3 A resolution, determination of the crystal structures of OPR1 in complex with the ligand p-hydroxybenzaldehyde, structural comparison with the OPR1:(9R,13R)-12-oxophytodienoate complex and further biochemical and mutational analyses reveals that 2 active-site residues, Tyr78 and Tyr246 in OPR1 are critical for substrate filtering | Solanum lycopersicum |

1.3.1.42 | F74Y | OPR3 mutant, change in substrate specificity, similar increase in stereoselectivity is observed for the mutant as compared to the wild-type enzyme | Solanum lycopersicum |
1.3.1.42 | F74Y/H244Y | OPR3 double-mutant, reduction of (9S,13S)-12-oxo-phytodienoic acid is slower in the double-mutant as in the wild type enzyme and the single mutants, the protein crystallizes as a monomer with none of the dimer interactions retain | Solanum lycopersicum |
1.3.1.42 | H244Y | OPR3 mutant, change in substrate specificity, similar increase in stereoselectivity is observed for the mutant as compared to the wild-type enzyme | Solanum lycopersicum |
