Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 6.3.1.5

Enzymes and Genes:
NAD synthetase, NH3-dependent Inferred from experiment : nadE

In Pathway: NAD biosynthesis I (from aspartate)

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

Enzyme Commission Synonyms: NAD synθse, NAD synthase, nicotinamide adenine dinucleotide synθse, diphosphopyridine nucleotide synθse

Summary:
A reaction in the biosynthesis of NAD. Glutamine can also serve as an amido group donor.

Enzyme Commission Summary:
L-Glutamine also acts, more slowly, as amido-donor [cf. EC 6.3.5.1].
