In enzymology, sequoyitol dehydrogenase (EC 1.1.1.143) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
 
H+
Sequoyitol dehydrogenase
 
H+
 
+ NADH
 

The two substrates of this enzyme are sequoyitol and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 2D-5-O-methyl-2,3,5/4,6-pentahydroxycyclohexanone, reduced NADH, and a proton. [1] [2]

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.
