Figure 2 Perrhenate binding sites. (a) A stereoview of a
simulated-annealing composite omit map (2F[o] - F[c]) contoured
at 1 illustrates
the environment of four rhenium ions in the protein. The figure
was generated using SETOR (Evans, 1993[Evans, S. (1993). J. Mol.
Graph. 11, 134-138.]) and Photoshop (Adobe). (b) A GRASP surface
representation of EsaI in stereoview colored according to the
calculated electrostatic potential with the most electronegative
regions colored in red, and the most electropositive in blue
(Nicholls et al., 1993[Nicholls, A., Bharadwaj, R. & Honig, B.
(1993). Biophys. J. 64, A166.]). The five positively identified
perrhanate ions, based on their anomalous signal by SOLVE, are
shown as green spheres.
