  • Glucose Dehydrogenase/Cytochrome Fusion Protein
    Publication number: 20130240374
    Abstract: A fusion protein of pyrroloquinoline quinone glucose dehydrogenase (PQQGDH) and a cytochrome is disclosed. PQQGDH is, for example, a water-soluble PQQGDH derived from Acinetobacter calcoaceticus. The cytochrome is, for example, an electron transfer domain of quinohemoprotein ethanol dehydrogenase from Comamonas testosteroni. The fusion protein of the present invention shows intramolecular electron transfer from PQQ, a redox center, to the cytochrome, which allow construction of a direct electron transfer-type glucose sensor which requires no electron mediators.

  • Method for measuring substrate concentration and apparatus for measuring substrate concentration
    Patent number: 8535510
    Abstract: This invention provides a substrate concentration measuring method for measuring a concentration of a substrate included in a specimen based on an output for measurement from an enzyme electrode when the enzyme electrode and the substrate are reacted with each other, the substrate concentration is calculated using an output for correction from the enzyme electrode obtained when a reference solution whose substrate concentration is known and the enzyme electrode are reacted with each other before or after the enzyme electrode and the substrate are reacted with each other. For example, the output for correction is measured by each specimen. In this method, the substrate concentration may be calculated using the output for correction for the specimen to be measured and an output for correction corresponding to the at least one other specimen and measured prior to the output for correction.
