  • Title: NnrA is required for full virulence and regulates several Brucella melitensis denitrification genes.
    Author: Haine V, Dozot M, Dornand J, Letesson JJ, De Bolle X.
    Journal: J Bacteriol; 2006 Feb; 188(4):1615-9. PubMed ID: 16452445.
    Abstract:
    We identified two regulators of denitrification genes in Brucella melitensis 16M: NarR, which regulates the nitrate reductase (nar) operon, and NnrA, which is involved in the expression of the last three reductases of the denitrification pathway (nirK, norB, and nosZ). NnrA is required for virulence in mice and for intracellular resistance to nitric oxide.
