1.1.1.47 | beta-D-glucose + NADP+ |
GDH-2 is absolutely specific for D-glucose. D-galactose, D-allose, D-mannose, D-xylose, L-arabinose, D-ribose, D-xylose, D-arabinose, L-xylose, D-glucosamine, 2-deoxy-D-glucose, D-fucose, D-lactose, D-maltose, D-fructose and ethanol were not used as substrates. kcat/Km of NADP+ is about 8fold higher compared to kcat/Km of NAD+ |
