In 2015 the laboratory that had characterized the ''Bacillus azotoformans'' enzyme wrote, "The copper-A-dependent Nor from Bacillus azotoformans uses cytochrome c<sub>551</sub> as electron donor but lacks menaquinol activity, in contrast to our earlier report."<ref>{{cite journal | vauthors = Al-Attar S, de Vries S | title = An electrogenic nitric oxide reductase | journal = FEBS Letters | volume = 589 | issue = 16 | pages = 2050–7 | date = July 2015 | pmid = 26149211 | doi = 10.1016/j.febslet.2015.06.033 | doi-access =  }}</ref>
