Introduction: Electron Transfer in Biological Systems In many biological processes, including oxidative phosphorylation and photosynthesis, electron transfer reactions play vital roles. Electrons must be transported at catalytically relevant rates and with specificity to prevent indiscriminate electron transfer that would quickly bring cells to equilibrium. To meet these requirements, biological systems employ a panoply of organic and inorganic redox centers, most of which are sequestered within proteins. In addition to protecting a cofactor from undesirable reactions, the surrounding protein environment tunes its redox properties and mediates specific contacts with other molecules. This brief overview describes the types of redox centers used in biology, the application of electron transfer theory to physiological systems, the kinetic complexity introduced by interprotein interactions, and general mechanisms for regulating biological electron transfer.
