General annotation (Comments)

Function

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. HAMAP-Rule MF_00361

Catalytic activity

ATP + NAD+ = ADP + NADP+. HAMAP-Rule MF_00361

Cofactor

Divalent metal ions By similarity. HAMAP-Rule MF_00361

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00361.

Sequence similarities

Belongs to the NAD kinase family.
