Summary
Protein surfaces have internal interactions that affect biological function. Ligands must compete with these interactions, not just water, for protein binding.
Area of Science:
- Biochemistry
- Structural Biology
- Protein Science
Background:
- Protein surface structure dictates biological function.
- Ligand binding involves competition with water and small molecules.
- Protein-ligand interactions are crucial for molecular recognition.
Purpose of the Study:
- To investigate intramolecular interactions at protein surfaces.
- To understand how these surface interactions influence ligand binding.
- To highlight a less obvious aspect of protein-ligand competition.
Main Methods:
- Analysis of structural surveys.
- Review of experimental studies.
- Computational modeling and analysis.
Main Results:
- Intramolecular interactions exist on protein surfaces.
- These surface interactions can be altered upon ligand binding.
- Ligands compete with both solvent and internal protein surface interactions.
Conclusions:
- Protein surface interactions are a significant factor in ligand binding.
- Understanding these intramolecular dynamics is key to predicting protein function.
- Ligand design should consider competition with protein surface energetics.
