Engineering protein structure for electron transfer function in photosynthetic reaction centers.
A basic relationship is defined that incorporates the three parameters that effectively modulate the rate of intraprotein electron transfer, namely distance, free energy and reorganization energy. This empirically validated relationship is used to explore the minimal requirements for protein-catalyzed conversion of excited electronic states into stable charge separated states, the essence of photosynthesis.
