NAD kinase

spinqualitylabelsall models NAD kinase complex with NADP and sulfate (PDB code 1z0u) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function NAD 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. See NAD and NAD(P)H. Structural highlights NADP is bound to NADK in a cleft between the N and C-terminal domains in the dimer interface. Water molecules are shown as red spheres.
