?2 -Adrenergic Receptor Activation by Agonists Studied with (19) F NMR Spectroscopy.
Angew Chem Int Ed Engl. 2013 Aug 16;
Authors: Horst R, Liu JJ, Stevens RC, Wüthrich K
Abstract
Proteins in slow motion: (19) F NMR studies indicate that equilibria between active and inactive states of the human ?2 -adrenergic receptor require extensive structural rearrangements (arrows in picture). This was shown by an enthalpy difference of ?Ho ?40 kJ mol(-1) and a slow exchange rate, with kex
