The Dilemma of Conformational Dynamics in Enzyme Catalysis: Perspectives from Theory and Experiment

  • Chapter
  • First Online:
Protein Conformational Dynamics

Part of the book series: Advances in Experimental Medicine and Biology ((AEMB,volume 805))

Abstract

The role of protein dynamics in catalysis is a contemporary issue that has stirred intense debate in the field. This chapter provides a brief overview of the approaches and findings of a wide range of experimental, computational and theoretical studies that have addressed this issue. We summarize the results of our recent atomistic molecular dynamic studies on cis-trans isomerase. Our results help to reconcile the disparate perspectives regarding the complex role of enzyme dynamics in the catalytic step and emphasize the major contribution of transition state stabilization in rate enhancement.
