Abstract
An assay method for a component in a specimen containing any one of ATP, deamide-NAD and an amide donor which comprises performing a main reaction which comprises incubating the specimen with NAD synthetase in the presence of ATP, deamide-NAD, an amide donor and Mg.sup.++ to generate NAD; performing a coenzyme cycling reaction by combining the oxidation-reduction reaction system with coenzyme NAD and the oxidation-reduction reaction system with coenzyme reduced NAD, and measuring a consumed or generated component in the cycling reaction. The NAD synthetase can be produced by culturing the microorganism Bacillus licheniformis B-0844 FERM P-6809, in a culture medium, and isolating the thus-produced NAD synthetase therefrom.
