'''STRUCTURE OF THE PERIPLASMIC CYTOCHROME C NITRITE REDUCTASE FROM ESCHERICHIA COLI'''<br />

==Overview==
The crystal structure and spectroscopic properties of the periplasmic, penta-heme cytochrome c nitrite reductase (NrfA) of Escherichia coli are, presented. The structure is the first for a member of the NrfA subgroup, that utilize a soluble penta-heme cytochrome, NrfB, as a redox partner., Comparison to the structures of Wolinella succinogenes NrfA and, Sulfospirillum deleyianum NrfA, which accept electrons from a, membrane-anchored tetra-heme cytochrome (NrfH), reveals notable, differences in the protein surface around heme 2, which may be the docking, site for the redox partner. The structure shows that four of the NrfA, hemes (hemes 2-5) have bis-histidine axial heme-Fe ligation. The catalytic, heme-Fe (heme 1) has a lysine distal ligand and an oxygen atom proximal, ligand.
