Native Bacillus stearothermophilius NAD Synthetase

Cat No.
NATE-0471
Description
In enzymology, a NAD+ synthase (EC 6.3.1.5) is an enzyme that catalyzes the chemical reaction:ATP + deamido-NAD+ + NH3↔ AMP + diphosphate + NAD+. The 3 substrates of this enzyme are ATP, deamido-NAD+, and NH3, whereas its 3 products are AMP, diphosphate, and NAD+. This enzyme belongs to the family of ligases, specifically those forming carbon-nitrogen bonds as acid-D-ammonia (or amine) ligases (amide synthases). This enzyme participates in nicotinate and nicotinamide metabolism and nitrogen metabolism.
