Abstract

An artificial photoinduced electron-transfer system has been constructed by accumulating redox cofactors in a myoglobin crystal. The crystal space allowed the construction of a site-specific dense array, and the different redox cofactors had low reorganization energies, as observed in native photosynthesis. A charge-separated state with a half-life 2800 times longer than that of one previously reported in organic solution was achieved.
