Figure 2
(a) The SEC-MALS chromatogram. The bar diagrams in (b) show the occupancies of atoms of the initially determined substructure as calculated with SHELXD (Sheldrick, 2015BB42) and the height of the anomalous map peak calculated with phases of the final structure by ANODE (Thorn & Sheldrick, 2011BB46). The drop after the 11th site indicates that only 11 Fe atoms are present. (c) The unit cell. One asymmetric unit is shown as a cartoon representation of the peptide backbone, with the covalently attached heme shown as as a ball-and-stick model and each chain coloured individually. The other asymmetric units are depicted as surface models coloured red, blue and green.
