Abstract
The detailed molecular dynamics of an actual bond-breaking event in a fluctuating enzyme substrate complex is simulated. The method developed allows one to explore what type of fluctuations are involved in enzymatic reactions and to evaluate entropic contributions to enzyme catalysis. The fluctuations of the enzyme electrostatic potential are found to be a key dynamical factor in reactions that involve a large change in the polarity of the reacting bonds.Mesh:
