Confirmation for conformational selection
NMR studies settle part of a long-standing debate about the mechanism used by the Hsp70 chaperone to recognize substrates.
متن کاملAntigen recognition by conformational selection.
Conformational adaptation between antigen and antibody can modulate the antibody specificity. The phenomenon has often been proposed to result from an 'induced fit', which implies that the binding reaction induces a conformational change in the antigen and the antibody. Thus, an 'induced fit' requires initial complex formation followed by a conformational change in the complex. However, an anti...
متن کاملConformational selection in protein binding and function.
Protein binding and function often involves conformational changes. Advanced nuclear magnetic resonance (NMR) experiments indicate that these conformational changes can occur in the absence of ligand molecules (or with bound ligands), and that the ligands may "select" protein conformations for binding (or unbinding). In this review, we argue that this conformational selection requires transitio...
متن کاملConformational selection in trypsin-like proteases.
For over four decades, two competing mechanisms of ligand recognition--conformational selection and induced-fit--have dominated our interpretation of protein allostery. Defining the mechanism broadens our understanding of the system and impacts our ability to design effective drugs and new therapeutics. Recent kinetics studies demonstrate that trypsin-like proteases exist in equilibrium between...
متن کاملDistinguishing induced fit from conformational selection.
The interactions between proteins and ligands often involve a conformational change in the protein. This conformational change can occur before (conformational selection) or after (induced fit) the association with ligand. It is often very difficult to distinguish induced fit from conformational selection when hyperbolic binding kinetics are observed. In light of a recent paper in this journal ...
