Nitrous Oxide Reductase NOR

Many organisms use oxidized nitrogen as a final electron acceptor in anaerobic respiration [33, 34]. This denitrification process can be described as a series of successive reducing steps NOJ NO2 NO N2O N2.

The expression and characterization of a recombinant subunit II of the archaebacterial terminal oxidase complex in Sulfolobus acidocaldarius was achieved. The binuclear CuA centre was shown to be correctly inserted. A protonation of one of the coordinating histidines was suggested from the pH-profile.109 The subunit is part of a supercomplex SoxM which also has been isolated in a catalytically competent form for the first time.110 Nitrous oxide reductase (NOR) was prepared from Hyphomicrobium denitrificans and charac-...
