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.
摘要
我们在布鲁氏菌16M中鉴定出两种反硝化基因的调节因子：NarR，它调节硝酸还原酶（nar）操纵子；以及NnrA，它参与反硝化途径中最后三种还原酶（nirK、norB和nosZ）的表达。NnrA是小鼠致病力以及细胞内对一氧化氮抗性所必需的。
