Todorovic, S.; Rodrigues, M.; Matos, D.; Pereira, I.
Redox properties of lysine- and methionine-coordinated hemes ensure downhill electron transfer in NrfH 2A 4 nitrite reductase (2012), J. Phys. Chem. B, 116, 5637-5643.

Crystallization (Commentary)

Crystallization (Comment)	Organism
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 midpoint redox potential of the NrfH menaquinol-interacting methionine-coordinated heme is -270 mV	Desulfovibrio vulgaris
