Charge Transfer in Biological Membranes


Abstract:
Electron and proton transfer are the key processes in biological energy
transduction machinery (photosynthesis and oxidative phosphorylation). Recent
theoretical and computational advances in treatment of electron and proton
transport in membrane proteins will be reviewed.  Applications in Cytochrome
Oxidase and other proteins will be discussed.
