Docking Stability And Electronic Structure Of Azurin-Cytochrome C(551) Complex System

We investigate the docking structure between cytochrome c(551) and azurin proteins by quantum mechanical calculation and molecular dynamics (MD). A model for the docking structure of the cytochrome-azurin complex is presented. We calculate the charge distribution around the active site for each protein and force field parameters to simulate the complex system by MD. We estimate some physical properties, such as binding free energy and the dynamical cross-correlation map. We discuss the stability of the cytochrome c(551)-azurin complex system.
