Identification of a sigma B-dependent small noncoding RNA in Listeria monocytogenes.

ABSTRACT: In Listeria monocytogenes, the alternative sigma factor sigma(B) plays important roles in stress tolerance and virulence. Here, we present the identification of SbrA, a novel small noncoding RNA that is produced in a sigma(B)-dependent manner. This finding adds the sigma(B) regulon to the growing list of stress-induced regulatory circuits that include small noncoding RNAs.
