Abstract

Background: Residue 138 situates in the hinge region connecting the DNA- and cAMP-binding domains of CRP. Results: A correlation was established among N-capping propensities and cooperativity of cAMP binding and affinity for lac-DNA. Conclusion: Our results provide a quantitative characterization of the N-capping properties of residue 138 in the allosteric activation event. Significance: The results provide the thermodynamic basis to the structural model of allostery.
