involved in catalysis. In the absence of Ca2+, substantial parts of the enzyme surrounding the binding sites for the copper ions show structural disorder. Reconstitution of the binuclear CuA site was possible in vitro but required the presence of Ca2+ ions for a stable insertion of the center |

the level of nosRZD transcripts is severely impaired in the nasT mutant. In the nasT background, deletions of either hairpin leads to increased level of nosRZD transcripts. Under denitrifying conditions, level of nosR, nosZ and nosD transcripts in the nasT mutant severely decrease compared with the nasS mutant and the wild-type, as for nosZ.

in Bradyrhizobium diazoefficiens, maximal expression of the nitrous oxide reductase gene nosZ requires oxygen limitation and the presence of a nitrogen oxide. In contrast to nosRZD coding region, nosR-leader transcript level was not affected by nasS or nasT mutations under aerobic or denitrifying conditions respectively. Mapping of two transcription start sites of nosR and identification of two potential hairpins, H1 and H2, within the 5'-leader of nosR transcripts, the two-hairpin RNA structure acts for transcription termination upstream of nosR and the binding of NasT to H1 facilitates read-through transcription to induce nos expression |
