Figure 1. Figure 1. Structure of H. pylori NAD^+ synthetase. (A) Stereo view of a ribbon diagram showing the dimeric structure of NAD^+ synthetase. The -helices are labeled A- L, and the -strands are labeled A- D. The two subunits are colored green and blue. The bound NaAD and ATP molecules are shown as the ball-and-stick models. The red line indicates a flexible loop region (residued 179-191). (B) Stereo view of the ATP binding site. Residues of the P-loop are colored cyan. (C) Stereo view of the NaAD binding site.
