## Abstract Sixβcoordinated heme groups are involved in a large variety of electron transfer reactions because of their ability to exist in both the ferrous (Fe^2+^) and ferric (Fe^3+^) state without any large differences in structure. Our studies on hemes coordinated by two histidines (bisβHis) an
