Figure 6

Comparison of the active sites of DsbA-like proteins. Proteins are in cartoon representation with notable residues in stick representation, with oxygen, nitrogen and sulfur colored red, blue and yellow, respectively. In panels B-D, active site waters are not shown for clarity. A. Mt-DsbA (PDB ID: 4IHU) in blue and waters are depicted as red spheres. B. Ec-DsbA (PDB ID: 1DSB, [40]) in green superimposed upon Mt-DsbA in blue, residue numbering for Ec-DsbA. C. Sa-DsbA (PDB ID: 3BCI, [31]) in salmon superimposed upon Mt-DsbA in blue, residue numbering for Sa-DsbA. D. Wp-DsbA (PDB ID: 3F4T, [42]) in orange superimposed upon Mt-DsbA in blue, residue numbering for Wp-DsbA.
