Regulation Of The Mazef Toxin-Antitoxin Module In Staphylococcus Aureus And Its Impact On Sigb Expression, Niles P. Donegan, Ambrose L. Cheung
Dartmouth Scholarship
In Staphylococcus aureus, the sigB operon codes for the alternative sigma factor σBand its regulators that enable the bacteria to rapidly respond to environmental stresses via redirection of transcriptional priorities. However, a full model of σBregulation in S. aureus has not yet emerged. Earlier data has suggested that mazEF, a toxin-antitoxin (TA) module immediately upstream of the sigB operon, was transcribed with the sigB operon. Here we demonstrate that the promoter PmazE upstream of mazEF is essential for full σB activity and that instead of utilizing autorepression typical of TA systems, sigB …
