Long-distance electron transfer (ET) plays an essential role in biological energy conversion. [1–5] Representative is those in photosynthetic reaction centers in which photon energy is converted to electrochemical energy via series of ETs through redox centers embedded in transmembrane protein. A simple but fundamental question open to microscopic investigation is how the protein environment is involved in the ET; the protein structure could be involved passively by simply holding the redox centers at appropriate spatial configuration or actively by providing intermediate virtual states for superexchange ET mechanism.
