A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 1.3.1.82

Accepted Name
(-)-isopiperitenone reductase.
Reaction catalysed
(+)-cis-isopulegone + NADP(+) <=> (-)-isopiperitenone + NADPH
Comment(s)
  • 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.
