Metals/Ions

Metals/Ions Comment Organism Structure
Fe 2 heme b, 1 heme c and 1 non-heme Paracoccus denitrificans
Fe heme c is six-coordinate, low-spin and in the NorC subunit and NorB contains one six-coordinate, low-spin heme b and a five-coordinate, high-spin heme b3, which, together with a non-heme iron atom, forms the dinuclear NO reduction site Paracoccus denitrificans
Fe the dinuclear NO reduction site Fe-O-Fe can adopt two different conformations named open and closed, closed is the dominant one Paracoccus denitrificans
