Energetics of Ligand-induced Conformational Flexibility in the Lactose Permease of Escherichia coli
Isothermal titration calorimetry has been applied to characterize the thermodynamics of ligand binding to wild-type lactose permease (LacY) and a mutant (C154G) that strongly favors an inward facing conformation. The affinity of wild-type or mutant LacY for ligand and the change in free energy (ΔG)...
