Abstract
For a long time, the small regulatory RNA DsrA has been considered as a regulator with a narrow spectrum of action due to its restricted targetome. Since the first reports on DsrA characterization, only two targets of DsrA have been described: rpoS and hns mRNAs, encoding the sigma factor σS and the nucleoid-associated protein H-NS, respectively. Recently, the scope of DsrA targetome has been expanded by the characterization of two negatively regulated mRNAs, mreB and rbsD, involved in cell wall biosynthesis and ribose metabolism, respectively. In this review, we summarize new insights in DsrA-mediated regulation and emphasize the versatility of DsrA modes of action.
