(Submitter supplied) We have shown that mitomycin C induces expression of the rsr-yrlBA-rtcBA operon in Salmonella Typhimurium in a manner that is dependent on the activator for this operon, RtcR. As such, treatment with mitomycin C generates the ligand or other cellular conditions that activate RtcR and likely generates the substrates on which the components of this RNA repair operon act. We performed an RNA-seq analysis on WT cells and cells with components of the RNA repair operon, or the activator of the operon, deleted with and without mitomycin C. more...

(Submitter supplied) Salmonella enterica serotype Typhimurium produces a variety of fimbrial appendages, among which the type 1 fimbriae is the most common type. In vitro static broth culture favors S. Typhimurium to produce type 1 fimbriae, while solid agar inhibits its expression. A transposon inserted in the stbC gene, which would encode an usher protein for Stb fimbriae of a non-flagellar S. Typhimurium LB5010 strain, conferred it to agglutinate yeast cells on both cultures, and was mannose-sensitive. more...

(Submitter supplied) The SOS response is a conserved pathway that is activated under certain stress conditions and is regulated by the repressor LexA and the activator RecA. The food-borne pathogen Listeria monocytogenes contains RecA and LexA homologs, but their roles in Listeria have not been established. In this study, we identified the SOS regulon in L. monocytogenes by comparing the transcription profiles of the wild-type strain and the ΔrecA mutant strain after exposure to the DNA damaging agent mitomycinC (MMC). more...

(Submitter supplied) Cell to cell communication in bacteria to regulate various cellular processes with respect to their population density is termed quorum sensing and is achieved using signaling molecules called autoinducers. LuxS, which is involved in the synthesis of the autoinducer molecule-2 (AI-2), is conserved in several Gram-positive and Gram-negative bacteria including the enteric pathogen Salmonella Typhimurium. more...
