  • Flavin-bound glucose dehydrogenases, a method for producing a flavin-bound glucose dehydrogenase, and yeast transformant used for the same
    Patent number: 9469844
    Abstract: A heat-resistant flavin-bound glucose dehydrogenase having a high substrate specificity for D-glucose, an method for producing the same, and a transformant used for the same. A flavin-bound glucose dehydrogenase gene encoding a flavin-bound glucose dehydrogenase derived from Mucor is introduced into yeast, Zygosaccharomyces, to obtain a transformant. Subsequently, the yeast transformant is cultured to obtain a flavin-bound glucose dehydrogenase from the culture. The heat-resistant flavin-bound glucose dehydrogenase is less susceptible to the effects of dissolved oxygen and allows accurate measurement of glucose even in the presence of sugar compounds other than glucose in a sample.
