Figure 4
Front (a) and back (b) views of electrostatic surfaces from several NTDs originating from closely related viruses. The structure of the SARS-CoV NTD was measured in solution by NMR, while the other structures were all obtained by single-crystal X-ray diffraction. Surfaces were calculated by APBS and truncated from −5 mV (red) to +5 mV (blue). |
