Molecular recognition by induced fit: how fit is the concept?

News Physiol Sci. 2001 Aug;16:171-3. doi: 10.1152/physiologyonline.2001.16.4.171.

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.
