General annotation (Comments)

Function	Involved in the oxidation of myo-inositol (MI) and D-chiro-inositol (DCI) to 2-keto-myo-inositol (2KMI or 2-inosose) and 1-keto-D-chiro-inositol (1KDCI), respectively By similarity. HAMAP MF_01671
Catalytic activity	Myo-inositol + NAD+ = 2,4,6/3,5-pentahydroxycyclohexanone + NADH. HAMAP MF_01671 D-chiro-inositol + NAD+ = 2,3,5/4,6-pentahydroxycyclohexanone + NADH. HAMAP MF_01671
Pathway	Polyol metabolism; myo-inositol degradation into acetyl-CoA; acetyl-CoA from myo-inositol: step 1/7. HAMAP MF_01671
Subunit structure	Homotetramer By similarity. HAMAP MF_01671
Sequence similarities	Belongs to the gfo/idh/mocA family.
