摘要： The present invention provides a microorganism-derived soluble coenzyme-binding glucose dehydrogenase which catalyzes a reaction for oxidizing glucose in the presence of an electron acceptor, has an activity to maltose as low as 5% or less, and is inhibited by 1,10-phenanthroline. The invention also provides a method for producing the coenzyme-binding glucose dehydrogenase, and a method and a reagent for measuring employing the coenzyme-binding glucose dehydrogenase. According to the invention, the coenzyme-binding glucose dehydrogenase can be applied to an industrial field, and a use becomes possible also in a material production or analysis including a method for measuring or eliminating glucose in a sample using the coenzyme-binding glucose dehydrogenase as well as a method for producing an organic compound. It became also possible to provide a glucose sensor capable of accurately measuring a blood sugar level. Therefore, it became possible to provide an enzyme having a high utility, such as an ability of being used for modifying a material in the fields of pharmaceuticals, clinical studies and food products.

摘要： The present invention provides members that produce on a large scale a coenzyme-linked glucose dehydrogenase which has excellent substrate-recognizing ability toward glucose while providing low action on maltose. The present invention relates to a polynucleotide encoding a soluble coenzyme-linked glucose dehydrogenase that catalyzes the oxidation of glucose in the presence of an electron acceptor and has an activity toward maltose of 5% or lower; a polypeptide encoded by the nucleotide sequence of the polynucleotide; a recombinant vector carrying the polynucleotide; a transformed cell produced using the recombinant vector; a method for producing a polypeptide comprising culturing the transformed cell and collecting from the cultivated products a polypeptide that links to FAD to exert the glucose dehydration activity; a method for determination of glucose using the polypeptide; a reagent composition for determination of glucose; and a biosensor.
