specific activity analysis of Aspergillus niger XyrB shows that the enzyme is able to convert a wide range of sugars and polyols. XyrB shows the highest specific activity towards D-galactose, D-xylose and L-arabinose. The enzyme is also active with D-glucose, D-mannose, D-fructose, L-sorbose, D-ribose, D-arabinose, L-xylose, and L-rhamnose in the reductive reaction, and with ribitol, D-arabitol, sorbitol, mannitol, and glycerol in the oxidative reaction |

the enzyme prefers NADPH as cofactor and shows broad substrate specificity, cf. EC 1.1.1.21. The enzyme is active with D-erythrose, D-ribose, D-arabinose, D-xylose, D-lyxose, D-allose, D-altrose, D-glucose, D-mannose, D-gulose, D-idose, and D-galactose. o activity with D-talose, fructose, sucrose, maltose, lactose, cellobiose, and xylobiose |
