Figure 3
Structural comparison of apo TtFbpA and Fe3+-bound TtFbpA. (a) Apo TtFbpA (pH 5.2; PDB entry 3wae ), (b) Fe3+–bicarbonates–TtFbpA (pH 5.5; PDB entry 3waf ), (c) apo TtFbpA (pH 7.5; PDB entry 4elo ) and (d) Fe3+–carbonate–TtFbpA (pH 7.5; PDB entry 4elr ). (a), (b) and (c) are in the open conformation, whereas (d) is in the closed conformation. The structures are aligned at their C-terminal domains.
