EC Number: 18.104.22.168
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
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 22.214.171.124].
