Extended Data Figure 4

The ligand environment of a, Mn1D, b, Mn2C, c, Mn3B and d, Mn4A are drawn in stereo view. The ligand bonds involving O5 coordination are slightly longer than the others in both Mn1D and Mn4A. Note that Mn1D is in a pseudo-five-coordinated, trigonal bipyramidal geometry with additional weak interaction to O5. Colour code: grey, manganese; green, carbon; blue, nitrogen; red, oxo-oxygen; yellow, O5; orange, water.
