The cytochromec nitrite reductase is isolated from the membranes of the sulfate-reducing bacteriumDesulfovibrio desulfuricansATCC 27774 as a heterooligomeric complex composedby two subunits (61 kDa and19 kDa) containing c-type hemes, encoded by the genes nrfA and nrfH, respectively. The extracted complex has in average a 2NrfA:1NrfH composition. The separation of ccNiR sub-units from one another is accomplished by gel filtration chromatography in the presence of SDS.
