(Submitter supplied) While many general RNA-binding proteins have been described in eukaryotes, the small RNA chaperone Hfq and the translational regulator CsrA remain the only known global RNA-associated cofactors involved in the bacterial post-transcriptional gene expression control. Here, using an RNA-seq-based analysis of the biochemically partitioned ensemble of cellular RNAs, we uncovered a large group of transcripts that interact with the RNA-binding protein ProQ in Salmonella enterica. more...

(Submitter supplied) FinO-domain proteins such as ProQ of the model pathogen Salmonella enterica have emerged as a new class of major RNA-binding proteins in bacteria. ProQ has been shown to target hundreds of transcripts including mRNAs from many virulence regions but its role, if any, in bacterial pathogenesis has not been studied. Here, using a Dual RNA-seq approach to profile ProQ-dependent gene expression changes as Salmonella infects human cells, we reveal dysregulation of bacterial motility, chemotaxis and virulence genes which is accompanied by altered mitogen-activated protein kinase signaling in the host. more...

(Submitter supplied) ProQ has become a paradigm for the emerging family of FinO domain-containing RNA binding proteins. ProQ in Salmonella enterica has been shown to act as a global RNA binding protein as it interacts with a plethora of sRNAs and mRNAs. However, little was known about processes ProQ regulates in Salmonella which have precluded to functionally characterize ProQ in vivo. In here, we show that ProQ represses the utilization of succinate as carbon source. more...

(Submitter supplied) Stable protein complexes, including those formed with RNA, are major building blocks of every living cell. Escherichia coli has been the leading organism with respect to global bacterial protein-protein networks. However, there has been no global census of RNA/protein complexes in this model species of microbiology. Here, we performed Grad-seq to establish an RNA/protein complexome, reconstructing sedimentation profiles in a glycerol gradient for ~85% of all E. more...

(Submitter supplied) RNA-protein interactions crucially underlie many steps of bacterial gene expression including post-transcriptional control by small regulatory RNAs (sRNAs). In stark contrast with recent progress in Gram-negative bacteria, knowledge about RNA and protein complexes in Gram-positive species remains scarce. Here, we used Grad-seq to draft a landscape of such complexes in Streptococcus pneumoniae, determining the sedimentation profiles of ~88% of the transcripts and ~62% of the proteins of this important human pathogen. more...

(Submitter supplied) Bacteria possess many small noncoding RNAs whose regulatory roles in pathogenesis are little understood due to a paucity of macroscopic phenotypes in standard virulence assays. Here, we use a novel Dual RNA-seq approach for a single-step simultaneous RNA profiling in both pathogen and host to reveal molecular phenotypes of sRNAs during infection with Salmonella Typhimurium. We identify a new PhoP/Q-activated small RNA which upon bacterial internalization acts to temporally control the expression of both, invasion-associated effectors and virulence genes required for intracellular survival. more...
