Figure 3
Pairwise comparison of the α+β core-domain structures of three PF02663 homologs. (a) Stereo diagram showing the superposition of the ribbon traces for (a) B8FYU2_DESHY (PDB code 2glz ; green) and Q9HJ63_THEAC (PDB code 2gvi ; red). The Zn/Ni atoms in B8FYU2_DESHY are shown as green spheres and the Zn atoms from Q9HJ63_THEAC are shown as red spheres. (b) Stereo diagram showing the superposition of the ribbon traces for B8FYU2_DESHY (PDB code 2glz ; green) and Q2LQ23_SYNAS (PDB code 3d00 ; blue). The Zn/Ni atoms in B8FYU2_DESHY are shown as green spheres and the chloride ions from Q2LQ23_SYNAS are shown as blue spheres. (c) Stereo diagram showing the superposition of the ribbon traces for Q9HJ63_THEAC (PDB code 2gvi ; red) and Q2LQ23_SYNAS (PDB code 3d00 ; blue). The Zn/Ni atoms in Q9HJ63_THEAC are shown as red spheres and the chloride ions from Q2LQ23_SYNAS are shown as blue spheres.
