In this work,two reconstituted myoglobins(rMb),ZnPP-F43H/H64A Mb and CoPP-F43H/H64A Mb,were prepared by replacing the natural heme of F43H/H64A Mb with zinc protoporphyrin(ZnPP) and cobalt protoporphyrin(CoPP).Their photostability and photocatalytic activity for dye deg...MORE In this work,two reconstituted myoglobins(rMb),ZnPP-F43H/H64A Mb and CoPP-F43H/H64A Mb,were prepared by replacing the natural heme of F43H/H64A Mb with zinc protoporphyrin(ZnPP) and cobalt protoporphyrin(CoPP).Their photostability and photocatalytic activity for dye degradation were also studied.The results showed that a...
