NAD synthase

<StructureSection load='1xng' size='350' side='right' caption='NAD+ synthase complex with Mg+2 (green), ATP (stick model) and deamino-NAD (PDB entry 1xng)' scene=>

FunctionFunction

NAD+ synthase (NADS) catalyzes the conversion of ATP, deamino-NAD+ and NH₃ to AMP, NAD+ and diphosphate (PP). NADS is part of the NAD synthesis pathway . See NAD.

Structural highlightsStructural highlights

The ATP binding site contains Mg+2 ion. The NAD binding site is located in the interface of the 2 subunits.
