NAD kinase

Gene

nadK

Organism
Photobacterium profundum (strain SS9)
Status
Reviewed-Annotation score: -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.UniRule annotation

Catalytic activityi

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