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 ...
