1.1.1.18 1-oxo-D-chiro-inositol + NADH + H+ - 1.1.1.18 D-2,3-diketo-4-deoxy-epi-inositol + NADH - 1.1.1.18 additional information the enzyme shows a broad substrate spectrum while remaining highly stereoselective. BsIDH is able to oxidize the mono-saccharides alpha-D-glucose and alpha-D-xylose but not beta-D-glucose, D-mannose and D-galactose 1.1.1.18 myo-inositol + NAD+ - 1.1.1.18 myo-inositol + NAD+ involved in rhizopine utilization 1.1.1.18 myo-inositol + NAD+ should be classified as A-type enzyme 1.1.1.18 myo-inositol + NAD+ involved in nitrogen fixation and nodulation of soybean 1.1.1.18 myo-inositol + NAD+ 75 times lower activity compared to the reverse reaction 1.1.1.18 myo-inositol + NAD+ first enzyme in the catabolic pathway of myo-inositol 1.1.1.18 myo-inositol + NAD+ the NAD+-dependent enzyme catalyses the oxidation of the axial hydroxyl group of myo-inositol to form scyllo-inosose 1.1.1.18 pinitol + NADH + H+ i.e. 3-O-methyl-D-chiro-inositol. Bacillus subtilis can utilize pinitol as the sole carbon source via the same myo-inositol catabolic pathway
