  • Title: Complex chemical kinetics in single enzyme molecules: Kramers's model with fractional Gaussian noise.
    Author: Chaudhury S, Cherayil BJ.
    Journal: J Chem Phys; 2006 Jul 14; 125(2):24904. PubMed ID: 16848608.
    Abstract:
    A model of barrier crossing dynamics governed by fractional Gaussian noise and the generalized Langevin equation is used to study the reaction kinetics of single enzymes subject to conformational fluctuations. The direct application of Kramers's flux-over-population method to this model yields analytic expressions for the time-dependent transmission coefficient and the distribution of waiting times for barrier crossing. These expressions are found to reproduce the observed trends in recent simulations and experiments.
