Beschreibung
Zusammenfassung:	Disclosed herein are a gene (polynucleotide) encoding an FAD-conjugated glucose dehydrogenase which can be characterized by reactivity to glucose, thermal stability, substrate-recognition performance, and low activity for maltose; a process for the production of the enzyme using a transformant cell transfected with the gene; a method for the determination of glucose; a reagent composition for use in the determination of glucose; and a biosensor for use in the determination of glucose. An embodiment is a polynucleotide encoding an FAD-conjugated glucose dehydrogenase, comprising a polypeptide whose amino acid sequence comprises X1-X2-X3-X4-X5-X6, wherein X1 and X2 independently represent an aliphatic amino acid residue; X3 and X6 independently represent a branched amino acid residue; and X4 and X5 independently represent a heterocyclic amino acid residue or an aromatic amino acid residue.
