Figure 3
Superimposition of the main chain (a) and heme group (b) of different related cytochrome c₆ structures. The different structures are colour-coded by their respective PDB code. Along with the model obtained by NMR spectroscopy (PDB entry 1c6s), the two crystal structures presented here do not contain the insertion (⁶⁵LAGYKDGSKSL⁷⁵) labelled by an asterisk, but instead contain a much shorter almost straight connecting loop (Supplementary Fig. S2). The structure and position of the heme group are widely conserved, with a minor difference in the position of the attached carboxy groups in the model derived by NMR coloured light blue.
