Overall architecture of Rho. Overall structural representations of (a) ATP-bound Rho (this study) and (b) the AMPPNP-bound structure of Rho (PDB entry 1pvo; Skordalakes & Berger, 2003). (c) Distribution of surface histidine residues (blue) in the ATP-bound structure of Rho (this work). The spacings between the surface-exposed histidines are several nanometres and are comparable to the loading density of His-tagged proteins bound to Ni–NTA beads (Hayworth & Hermanson, 2014), which presumably allows multiple binding sites to Ni–NTA and contributes to the observed affinity of Rho for Ni–NTA resin. |
