  • L-threonine analysis method and L-threonine dehydrogenase
    Patent number: 8785147
    Abstract: A method for analyzing L-threonine contained in an specimen, which includes the steps of mixing a sample containing the specimen with an L-threonine dehydrogenase derived from Cupriavidus necator and a coenzyme NAD+ and analyzing the amount of NADH or 2-amino-3-oxobutyric acid after a predetermined period; an L-threonine dehydrogenase derived from Cupriavidus necator, which is a novel L-threonine dehydrogenase (TDH; EC 1.1.1.103) and can be utilized in the above-mentioned analysis method; a method for preparing a gene or the like to be used in the preparation of the enzyme, or a method for preparing the enzyme; an L-threonine analysis kit which includes (A) the L-threonine dehydrogenase and (B) a coenzyme NAD+; an enzyme preparation for use in the analysis of L-threonine, which includes the L-threonine dehydrogenase contained in a buffer solution; and an enzyme sensor utilizing the L-threonine dehydrogenase.
