Paracoccus denitrificans

Q51662

the enzyme forms a complex of two subunits, NorB and NorC. Subunit NorC is a membrane-anchored cytochrome c with one c-type heme, which presumably forms the site of electron entry. Subunit NorB subunit contains three redox centers: two b-type hemes (hemes b and b3) and a non-heme iron (FeB). Heme b3 and the non-heme iron form the binuclear center, where nitric oxide is bound and reduced, NorB homology structure modelling
