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. Can also use D-glucose and D-xylose, and shows a trace of activity with D-ribose and D-fructose. Source: Recombinant protein corresponding to aa1-344 from Bacillus subtilis Inositol 2-dehydrogenase/D-chiro-inositol 3-dehydrogenase, fused to 6X His-SUMO-Tag at N-terminal, expressed in E.coli.
