The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: NAD+ synthase (glutamine-hydrolysing)

Enzyme Commission Synonyms: NAD synthetase (glutamine-hydrolysing), nicotinamide adenine dinucleotide synthetase (glutamine), desamidonicotinamide adenine dinucleotide amidotransferase, DPN synthetase

A reaction in the biosynthesis of NAD. Ammonia can also serve as a nitrogen donor.

Enzyme Commission Summary:
NH3 can act instead of glutamine (cf. EC NAD+ synthase).
