Dynamic Aspects of Electron-Transfer Reactions in Metalloprotein Complexes
Various metalloproteins act as electron carriers and redox enzymes in photosynthesis, respiration, and other biological processes. Because these processes involve oxidation and reduction, that is, electron transfer, mechanisms of electron-transfer reactions involving metalloproteins are very important. Despite much recent research, molecular mechanisms of these reactions are only beginning to be understood.1-4 Because the protein enveloping metal complexes (often termed metal sites or metal centers) is an organic polymer, mechanisms of electron transfer through proteins may interest polymer scientists and other materials scientists, especially those who study electroconductive materials. If one understands how electrons are transferred over 10-20 Å or even longer distances between metal complexes in metalloproteins, one may be more successful in designing a synthetic electroconductive polymer.
