Abstract
A flavin-binding glucose dehydrogenase having high substrate specificity for D-glucose and decreased reactivity to D-xylose and/or maltose. More specifically, a flavin-binding glucose dehydrogenase having one or more amino acid substitutions at a position corresponding to position 78, position 79, position 81, position 121, position 122, position 123, position 569 and position 612 of Mucor-derived flavin-binding glucose dehydrogenase. The flavin-binding glucose dehydrogenase enables D-glucose to be measured accurately without being susceptible to the effects of the presence of D-xylose and/or maltose, even under conditions of mounting a large amount of an enzyme such as in glucose sensors.
