Structure-function and dynamics-function 
relationships in biomolecular electron transport systemss

Abstract:
Electron transfer reactions are ubiquitous in 
biology and in chemistry. In biology, electron 
transfer reactions are observed in both protein 
and DNA biomolecular systems. They are important 
for a variety of biochemical processes that 
include the bioenergetic pathways, and the 
controls of development and disease. Biological 
electron transfer mechanisms range from 
tunnelling to thermally activated hopping. The 
important determinants of a biomolecular electron 
transfer rate are the structure and the motion of 
the electron transfer molecule, and the nature of 
the electron donating and electron accepting states.
I give a brief introduction to the theory of 
biological electron transfer rates mediated by 
tunneling, and discuss current trends in this 
research field together with some recent results 
of simulations of protein electron transfer systems.
