  • Publication number: 20190177699
    Abstract: 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.

  • Publication number: 20190094235
    Abstract: [Problem to be solved] It is to provide a method for selectively and easily quantifying the L-form and/or D-form amino acids to be measured using an AARS with high sensitivity, and an amino acid quantification kit. [Solution to Problem] A method for quantifying amino acids (L-AA and/or D-AA) in a sample using an AARS, wherein the amino acids and the AARS are released from an aminoacyl AMP-AARS complex once formed, and they are used again for forming the aminoacyl AMP-AARS complex, so that reaction products such as pyrophosphoric acid to be measured can be ultimately produced up to a molar number larger than that of the amino acids contained in the sample, and an amino acid quantification kit for performing the method.
