Numerical calculation of protein-ligand binding rates through solution of the Smoluchowski equation using smooth particle hydrodynamics
Wenxiao Pan, Michael Daily, Nathan A. Baker
Background. The calculation of diffusion-controlled ligand binding rates is important for understanding enzyme mechanisms as well as designing enzyme inhibitors. We demonstrate the…
Fluorescence Correlation Spectroscopy and Nonlinear Stochastic Reaction-Diffusion
Mauricio J. Del Razo, Wenxiao Pan, Hong Qian +1
The currently existing theory of fluorescence correlation spectroscopy(FCS) is based on the linear fluctuation theory originally developed by Einstein, Onsager, Lax, and others as…
