Protein

NAD kinase

Gene
nadK, Mbar_A2191
Organism
Methanosarcina barkeri (strain Fusaro / DSM 804)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP By similarity.UniRule annotation

Catalytic activityi

ATP + NAD+ = ADP + NADP+.UniRule annotation

Cofactori

Divalent metal ions By similarity.UniRule annotation
