Figure 4. Electrostatic Surface Representation of KSCPSolid surface representation of the "front" side of KSCP shown in the same orientation as in Figure 1, and of the "back" side, obtained after a rotation of 180 around a vertical axis. The colors indicate the electrostatic surface potential at pH 7 contoured from +20 kT/e (dark blue) to -20 kT/e (dark red). White lines indicate the approximate position of the Ca^2+ binding residues Asp316 and Asp338. The image was generated with GRASP [44].
