Cloned(Commentary)

EC Number Cloned (Comment) Organism
1.7.2.5 the water-soluble domain of NorC, cytochrome c type, expressed in Escherichia coli Paracoccus denitrificans

Metals/Ions

EC Number Metals/Ions Comment Organism Structure
1.7.2.5 Fe 2 heme b, 1 heme c and 1 non-heme Paracoccus denitrificans
1.7.2.5 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
1.7.2.5 Fe heme c is bound via an Cys-Xxx-Xxx-Cys-His heme-binding motif Paracoccus denitrificans
