A process for producing glucose dehydrogenases. This process comprises transferring a DNA containing a sequence represented by SEQ ID NO:1 which encodes an α subunit having a glucose dehydrogenase activity and a β subunit being an electron transfer protein into a microorganism belonging to the genus Pseudomonas to thereby construct a transformant, and culturing this transformant so as to allow the production of a first glucose dehydrogenase containing the above-described β subunit and a second glucose dehydrogenase free from the β subunit. The α subunit as described above has a molecular weight of about 60 kDa measured by, for example, SDS-polyacrylamide gel electrophoresis under reducing conditions, while the β subunit as described above has a molecular weight of about 43 kDa measured by, for example, SDS-polyacrylamide gel electrophoresis under reducing conditions.
