X-ray crystallography ligand binding

  • How do ligands bind?

    Binding occurs by intermolecular forces, such as ionic bonds, hydrogen bonds and Van der Waals forces.
    The association or docking is actually reversible through dissociation.
    Measurably irreversible covalent bonding between a ligand and target molecule is atypical in biological systems..

  • Models of ligand binding are often based on four assumptions: (1) steric fit: that binding is determined mainly by shape complementarity; (2) native binding: that ligands mainly bind to native states; (3) locality: that ligands perturb protein structures mainly at the binding site; and (4) continuity: that small
  • Protein-ligand interactions are a necessary prerequisite for signal transduction, immunoreaction, and gene regulation.
    Protein-ligand interaction studies are important for understanding the mechanisms of biological regulation, and they provide a theoretical basis for the design and discovery of new drug targets.
X-ray crystallography has proven to be an invaluable tool in this respect, as it is able to provide exquisitely comprehensive structural information about the interaction of a ligand with a pharmacological target.
X-ray crystallography is a powerful technique for studying protein-ligand interactions. Advances in techniques have meant that it is now possible to routinely determine the structures of ligand complexes in the majority of cases where crystallization conditions and protein structures are already known.
