Figure 4
The conserved residues display large conformational flexibility. (a) Conserved residues on the potential binding surface of TmYeaZ (cyan) and StYeaZ (gray). The Cα positions of these residues are highlighted by spheres. The residues of StYeaZ are labeled in parentheses. (b) A stereoview of the unknown ligand (UNL; shown as red spheres) located between α1 and α2 of TmYeaZ (present in both monomers; the B monomer is shown here). The experimental density for the UNL (after solvent flattening and twofold averaging) is contoured at 1.5σ. Nearby protein residues are shown on stick representation. |
