The X-Ray Structure of the Ligand-Free Antibiotic Ristocetin-A Reveals the Role of the Monomer/Dimer Equilibrium in Its Binding Mode
Figure 4
Stereo view of the least squares superposition of the anti conformers of unbound and bound ristocetin-A subunits. In green, the anti(bent) sugar conformation subunit of our monoclinic ligand-free structure; in magenta the anti(bent) monomer of the biliganded structure. The acetyl-tripeptide of the bound form is shown in sphere representation.
