Figure 2
Phosphate and nucleotide binding in the phosphate-bound, ADP-bound and ATP-bound structures of NSP13. NSP13 is depicted in cartoon representation, showing the RecA1 domain (orange) and the RecA2 domain (blue). Phosphates are shown in ball-and-stick format coloured by atom, and the nucleotide is shown in cyan ball-and-stick format. Interacting residues are labelled and shown as sticks, with hydrogen bonds (red), salt bridges (yellow), π–π interactions (white), cation–π interactions (green) and donor–π interactions (blue) depicted. The polder OMIT mFo − DFc electron-density map for inorganic phosphate, ADP and ATP is displayed as a blue mesh contoured at the ≥3.5σ level. Nucleotide-binding sites are shown for the phosphate-bound structure (PDB entry 9i4v), with chain A in (a) and chain B in (b), the ADP-bound structure (PDB entry 9i51), with chain A in (c) and chain B in (d), and the ATP-bound structure (PDB entry 9i53), with chain A in (e) and chain B in (f). |
