Molecular recognition by induced fit: how fit is the concept?
1Department of Biochemistry, University of Zurich, CH-8057 Zurich, Switzerland.
Abstract:
Induced fit explains why biomolecules can bind together even if they are not optimized for binding. However, induced fit can lead to a kinetic bottleneck and does not describe every interaction in the absence of prior complementarity. Preselection of a fitting conformer is an alternative to induced fit.
