Figure 2

(A) Ribbon diagram of the (UreDFG)2 crystal structure from H. pylori (PDB id 4HI0) [44]. HpUreD, HpUreF, and HpUreG chains are colored in light green, yellow and dark red, respectively, with the darker and lighter portions highlighting the different monomers. The views in the top and bottom panel are rotated by 90° along the horizontal axis. The inset reports the position of the residues forming the HpUreG Cys-Pro-His conserved motif; (B) Comparison between the HpUreG dimeric crystal structure, as found in the Hp(UreDFG)2 complex, and the homology model structure calculated in ref. [47]; (C) Ribbon scheme of the structure of SpUreE homodimer (PDB id: 1EAR); the two monomers are colored in light blue, with the darker and lighter portions representing the two monomers. The views in the top and bottom panel are rotated by 90° along the horizontal axis. In the inset is reported the detail of the SpUreE metal binding site.
