Figure 2.
Figure 2. Surface conservation pattern and the nucleotide binding site of SSO1545. A: Molecular surface of SSO1545 colored by sequence conservation. The most conserved residues are shown in red, the nonconserved residues in white. The three domains of SSO1543 are shown in ribbon representation and colored as yellow, blue, and cyan, respectively. The orientation of left panel is the same as in Figure 1(A). B: Close-up stereo view of the ADP binding site. The bound ADP (yellow) and magnesium ion (silver) are shown in sticks and sphere, respectively. Walker A (P-loop, green), Walker B (W-B, blue), sensor I (S-I, cyan), sensor II (S-II, white) are shown in cartoon and sticks. The STAND-specific hhGRExE and GxP motifs are also highlighted in blue.
Figure 3.
Figure 3. Structural comparisons of SSO1545 with AAA+ ATPases with similar domain organizations: Orc1 (PDB 2v1u), RuvB (PDB 1in5), Orc2 (PDB 1w5t), and Apaf-1 (PDB 1z6t, residues 105-450). These structures were superimposed base on their respective NTPase domains (gray). The linker regions connecting the NTPase domain and the WH domain (green) are shown in red. The nucleotides and magnesium ions are shown in sticks and spheres, respectively.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
