A) Ribbon representation of Pf FeSOD polypeptide chain with colour ramping from the amino terminus in red to the carboxyl terminus in magenta. The iron is shown as a red sphere and its coordinating residues His26, His73, Asp157 and His161 are shown in cylinder representation. B) The Pf FeSOD dimer coloured by subunit with the Fe atoms as mauve spheres and their coordinating residues in cylinder representation. The figures were made using CCP4 mg [39].
