Function
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.
Catalytic activity
- NAD+ + ATP = ADP + NADP+ + H+
Cofactor
