Beschreibung
Zusammenfassung:	The present invention provides a glucose dehydrogenase having an improved specific activity. A polypeptide comprising an amino acid sequence having such a structure that an amino acid residue at position-578 is substituted by a valine residue or a phenylalanine residue in the amino acid sequence represented by SEQ ID NO: 1, and a variant of the polypeptide have an improved glucose dehydrogenase activity.
