Sequoyitol dehydrogenase

In enzymology, sequoyitol dehydrogenase is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are sequoyitol and oxidised nicotinamide adenine dinucleotide. Its products are 2D-5-O-methyl-2,3,5/4,6-pentahydroxycyclohexanone, reduced NADH, and a proton.
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 5-O-methyl-myo-inositol:NAD⁺ oxidoreductase. This enzyme is also called D-pinitol dehydrogenase.
