LITERATURE
the biological unit, NrfH2NrfA4, houses 28 c-type heme groups, 22 of them with low spin and 6 with pentacoordinated high spin configuration. The high spin hemes, which are the electron entry and exit points of the complex, carry a highly unusual coordination for c-type hemes, lysine and methionine as proximal ligands in NrfA and NrfH, respectively. The redox potential of the catalytic lysine-coordinated high spin heme of NrfA is -50 mV
