CC   -!- FUNCTION: Involved in the regulation of the intracellular balance of
CC       NAD and NADP, and is a key enzyme in the biosynthesis of NADP.
CC       Catalyzes specifically the phosphorylation on 2'-hydroxyl of the
CC       adenosine moiety of NAD to yield NADP. It can use ATP and other
CC       nucleoside triphosphates (UTP, CTP, GTP, dATP, TTP) as phosphoryl
CC       donors, while nucleoside mono- or diphosphates and poly(P) cannot.

CC       and NADPH at physiological concentrations, whereas inhibition by NADP
CC       is only slight. Inhibited by p-chloromercuribenzoate and HgCl(2).
