Characterization of Brucella abortus sigma factor sigma54 (rpoN): genetic complementation of Sinorhizobium meliloti ntrA mutant.

Microbial pathogenesis - 1 Jan 2000

Iannino Florencia, Ugalde Rodolfo A, Iñón de Iannino Nora

Abstract excerpt

The intracellular pathogen Brucella abortus has an alternative sigma factor sigma54 (RpoN) highly similar to Sinorhizobium meliloti NtrA. RpoN was described to be required for the transcription of a wide range of genes involved in diverse physiological functions including the regulation of virulence-related factors in both plants and animal pathogens. B. abortus rpoN gene restored the normal growth of an S....
