Abstract Background Interactions between transcription factors and their specific binding sites are a key component of regulation of gene expression. Until recently, it was generally assumed that most bacterial transcription factor binding sites are

Transcription sigma factors direct the selective binding of RNA polymerase holoenzyme (Eσ) to specific promoters. Two families of sigma factors determine promoter specificity, the σ70 (RpoD) family and the σ54 (RpoN) family. In transcription contr

The adaptation of Salmonella enterica serovar Typhimurium to stress conditions involves expression of genes within the regulon of the alternative sigma factor RpoN (σ54). RpoN-dependent transcription requires an activated bacterial enhancer binding

The regulated uptake and consumption of d-amino acids by bacteria remain largely unexplored, despite the physiological importance of these compounds. Unlike other characterized bacteria, such as Escherichia coli, which utilizes only l-Asp, Acinetobac

The intracellular small molecules 2',3'-cyclic nucleotide monophosphates (2',3'-cNMPs) have recently been rediscovered within both prokaryotes and eukaryotes. Studies in bacteria have demonstrated that 2',3'-cNMP levels affect bacterial phenotypes, s

Organismal adaptations to environmental stimuli are governed by intracellular signaling molecules such as nucleotide second messengers. Recent studies have identified functional roles for the noncanonical 2′,3′-cyclic nucleotide monophosphates (2

Transcriptional regulators in the LysR or GntR families are typically encoded in the genomic neighbourhood of bacterial genes for malonate degradation. While these arrangements have been evaluated using bioinformatics methods, experimental studies de

The σ54 regulon in Salmonella enterica serovar Typhimurium includes a predicted RNA repair operon encoding homologs of the metazoan Ro60 protein (Rsr), Y RNAs (YrlBA), RNA ligase (RtcB), and RNA 3′-phosphate cyclase (RtcA). Transcription from σ54

The variable sigma (σ) subunit of the bacterial RNA polymerase (RNAP) holoenzyme, which is responsible for promoter specificity and open complex formation, plays a strategic role in the response to environmental changes. Salmonella enterica serovar
