Patent ID: 8715990

Claim:
An isolated glucose dehydrogenase, which can be produced by Burkholderia cepacia KS1 strain (FERM BP-7306), having the following properties: (i) the enzyme has an action of catalyzing dehydrogenation reaction of glucose; (ii) the enzyme consists of at least one a subunit having a molecular weight of about 60 kDa and at least one β subunit which is cytochrome C having a molecular weight of about 43 kDa in SDS-polyacrylamide gel electrophoresis under a reducing condition; (iii) the enzyme shows a molecular weight of about 380 kDa in gel filtration chromatography using TSK Gel G3000SW; and (iv) the enzyme shows an optimal reaction temperature around 45° C. (Tris-HCl buffer, pH 8.0).
