(-)-isopiperitenone reductase.
based on mapping to UniProt Q6WAU1
(+)-cis-isopulegone + NADP(+) = (-)-isopiperitenone + NADPH.
-!- The reaction occurs in the opposite direction to that shown above. -!- Participates in the menthol-biosynthesis pathway of Mentha plants. -!- (+)-pulegone, (+)-cis-isopulegone and (-)-menthone are not substrates. -!- Has a preference for NADPH as the reductant, with NADH being a poor substitute. -!- Highly regioselective for the reduction of the endocyclic 1,2-double bond, and is stereoselective, producing only the 1R-configured product.
