This domain is found in Nitric oxide reductase subunit B from Pseudomonas aeruginosa (NorB) and similar bacterial sequences. NorB is the large component of the anaerobic respiratory chain that transforms nitrate to dinitrogen (denitrification). This entry represents the cytochrome C-like domain of NorB, which has 12 alpha-helices in the transmembrane region with two heme irons and and one non-heme iron [2].	Domain
