(−)-menthol dehydrogenase

A (−)-menthol dehydrogenase is an enzyme that catalyzes the chemical reaction


 * (−)-menthol + NADP$+$ $$\rightleftharpoons$$ (−)-menthone + NADPH + H$+$,

i.e., catalyses the breakdown of menthol. Thus, the two substrates of this enzyme are (−)-menthol and NADP$+$, whereas its 3 products are (−)-menthone, NADPH, and H$+$.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD$+$ or NADP$+$ as acceptor. The systematic name of this enzyme class is (−)-menthol:NADP$+$ oxidoreductase. This enzyme is also called monoterpenoid dehydrogenase. This enzyme participates in monoterpenoid biosynthesis.
