  Abstract
Biomolecular associations often accompanied by large conformational changes, sometimes folding and unfolding. By exploring an exactly solvable model, we constructed the free energy landscape and established a general framework for studying the biomolecular flexible binding process. We derived an optimal criterion for the specificity and function for flexible biomolecular binding where the binding and conformational folding are coupled.

Key Words: Binding with Large Conformational Changes, Binding-Folding Coupling, Biomolecular Recognition, Flexible Binding, Optimal Function, Optimal Specificity
