Abstract

Photosensitizers, Zn protoporphyrin IX and Zn chlorin e₆, are completely inserted into each heme pocket of a hexameric apohemoprotein. The fluorescence quenching efficiencies upon addition of methyl viologen are 2.3 and 2.6 fold-higher than those of the partially photosensitizer-inserted proteins, respectively, indicating that the energy migration occurs within the proteins.
