(+)-neomenthol dehydrogenase

Jump to: navigation, search

In enzymology, a (+)-neomenthol dehydrogenase (EC is an enzyme that catalyzes the chemical reaction

(+)-neomenthol + NADP+ (-)-menthone + NADPH + H+

Thus, the two substrates of this enzyme are (+)-neomenthol 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 (+)-neomenthol:NADP+ oxidoreductase. This enzyme is also called monoterpenoid dehydrogenase. This enzyme participates in monoterpenoid biosynthesis.
