Figure 2
Comparison of the manner of coordination-complex formation with a ferric ion in TtFbpA, MhFbpA and BpFbpA. The metal-binding sites of (a) Fe3+–bicarbonates–TtFbpA (PDB entry 3waf ; this work), (b) Fe3+–carbonate–MhFbpA (PDB entry 1si0 ; Shouldice et al., 2004  ), (c) Fe3+–carbonate–TtFbpA (PDB entry 4elr
; Wang et al., 2013) and (d) Fe3+–carbonate–BpFbpA (PDB entry 2owt
; S. A. L. Tom-Yew, B. H. Shilton, E. G. Bekker, E. I. Tocheva & M. E. P. Murphy, unpublished work) are shown. The three coordinating tyrosine residues are shown as stick models and the coordinated ferric ions and water molecules are shown as spheres. The orange and blue dotted lines represent coordinate and hydrogen bonds, respectively. The coordination in the six-coordinate (e) and five-coordinate (f) geometries of ferric ion is shown. |
