The ferroxidase centre. (a) Stereo figures of σA-weighted Fo − Fc density in the ferroxidase site contoured at 5σ, (b) superposition of the ferroxidase centre of the P213 structure (grey/orange) and the Mn-bound structure (yellow/purple; PDB code 1bcf
; Frolow et al., 1994) of E. coli bacterioferritin and (c) superposition of the FE2 site environment in the P213 E. coli bacterioferritin structure (grey) with the corresponding region in the structure of reduced A. vinelandii bacterioferritin (pale green; PDB code 1fkz
; Swartz et al., 2006). The location of the inner cavity (IC) is indicated. This view is rotated ∼90° with respect to the previous views. |
