Protein
NAD kinase
Gene
nadK, PYRAB09100, PAB1756
Organism
Pyrococcus abyssi (strain GE5 / Orsay)
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
