Figure 7
A plot showing the planarity of bound haem groups in structures representing the 13 different haem-binding protein families. The histogram shows the r.m.s. deviations from a calculated best-fit plane of all atoms in the core of the 19 haem groups present in the 13 representative structures, ordered by increasing r.m.s. Each protein is identified by its four-character PDB code and chain identifier in capitals where relevant. The numbers in brackets after the PDB codes refer to different haem molecules bound to the same chain. |
