(+)-pulegone reductase () is an enzyme with systematic name (âÂÂ)-menthone:NADP<sup>+</sup> oxidoreductase. This enzyme catalises the following chemical reaction
This enzyme, from peppermint converts (+)-pulegone to a mixture of (âÂÂ)-menthone and (+)-isomenthone using nicotinamide adenine dinucleotide phosphate (NADPH) as its cofactor. It does not act in the opposite direction
