Figure 4.
(a) Position of Cl^- (green sphere) located in the native
electron density (blue, contoured at 1.2 level)
close to the Mn[4]Ca cluster (red and orange spheres; Mn1 is
partially hidden behind Mn2). The coordinating amino acids are
from D1 (yellow) except for D2-Lys317 (orange). (b) Enlarged
view of the neighborhood of Cl^- showing coordinating amino
acids and electron density (blue, contoured at 1.2 level)
for a putative water molecule (purple sphere) located between
Mn4 and Cl^-. Distances are given in angstroms.
