FunctionNAD kinase or ATP-dependent NAD kinase (NADK) catalyzes the conversion of ATP and NAD to ADP and NADP. NADP is critical for metabolism, calcium signaling and anti-inflammatory processes. NADK is regulated by calmodulin-dependent mechanism[1]. See NAD and NAD(P)H. Structural highlightsin a cleft between the N and C-terminal domains in the dimer interface[2]. Water molecules are shown as red spheres.
