Abstract
A novel NAD synthetase is produced by culturing a broth of Bacillus stearothermophilus H-804 FERM BP-1408. This new enzyme selectively catalyzes the reaction ##STR1## without catalyzing the reaction ##STR2## The enzyme uses ammonia or ammonium ion as a substrate, but does not use either glutamine or asparagine. Also disclosed is an assay method using the enzyme, for any one of ATP, deamide-NAD, ammonia or ammonium ion in a specimen to be assayed.
