Figure 3: Stereo view of a hydrated K+ ion in the central
cavity. Eight water molecules (red spheres) surround a single
K+ ion (green sphere) in the cavity. The 2F[o] - F[c] electron
density map is contoured at 2 .
Residues forming the cavity are shown in ball-and-stick
representation. For clarity, only backbone atoms and the side
chains facing the cavity (Thr 75, Ile 100, Phe 103, Gly 104 and
Thr 107) are shown. The subunit closest to the viewer has been
removed.
