Hypothesis

Does molecular recognition gain any advantage by conformational changes?

Conclusion

Optimal specificity in molecular recognition is achieved when the ligand is slightly off target, suggesting that conformational mismatches can improve selectivity.

Supporting Evidence

  • Molecular recognition processes often involve conformational changes.
  • Optimal specificity is achieved when the ligand is slightly off target.
  • Conformational mismatches can improve the selectivity of molecular recognition.

Takeaway

Molecules need to fit together like puzzle pieces to work well, and sometimes being a little mismatched can actually help them find the right fit better.

Methodology

A statistical-mechanics model was introduced to study the effects of conformation and flexibility on molecular recognition processes.
