(Submitter supplied) Neisseria meningitidis is a human commensal that occasionally causes life-threatening infections such as bacterial meningitis and septicemia. Despite experimental evidence that gene regulation as well as the expression of small non-coding RNAs (sRNAs) affect meningococcal virulence, the organization of its transcriptome, including in particular the biogenesis of sRNAs and their mode of action, is only poorly understood. 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) In many bacteria, the base pairing between most small regulatory RNAs (sRNAs) and their targets is facilitated by the Hfq RNA chaperone. However, recent studies have shown FinO-domain proteins also bind sRNAs. To compare the contributions of Hfq and the FinO-domain ProQ protein in Escherichia coli, we carried out RIL-seq, which allows global identification of two RNAs bound to the same protein. We detected hundreds of RNA pairs on ProQ. more...

(Submitter supplied) Understanding RNA processing and turnover requires knowledge of cleavages by major endoribonucleases within a living cell. We have employed TIER-Seq (transiently inactivating an endoribonuclease followed by RNA-Seq) to profile cleavage products of the essential endoribonuclease RNase E in Salmonella enterica. A dominating cleavage signature is the location of a uridine two nucleotides downstream in a single-stranded segment, which we rationalize structurally as a key recognition determinant that may favor RNase E catalysis. more...

(Submitter supplied) RNA-based regulation of gene expression is substantially contributing to the ability of bacteria to rapidly adapt to changing environmental conditions. This study employs RNAseq to define the transcriptome of Caulobacter in response to treatment with the DNA-crosslinking agent mitomycin C. We identify a small, regulatory RNA ChvR synthesized under the control of the conserved ChvIG two-component system which represses production of a TonB-dependent receptor, ChvT, in Caulobacter crescentus. more...

(Submitter supplied) MicF is a textbook example of a small regulatory RNA (sRNA) that acts on a trans-encoded target mRNA through imperfect base paring. The discovery of MicF as a post-transcriptional repressor of the major Escherichia coli porin OmpF established the paradigm for a meanwhile common mechanism of translational inhibition, through antisense sequestration of a ribosome binding site. However, whether MicF regulates additional genes has remained unknown for almost three decades. more...

(Submitter supplied) The Ydr374c is the only protein that has the YTH domain in Saccharomyces cerevisiae. The YTH domain was identified by comparing all known protein sequences with the YT521-B splicing factor, and it is found only in eukaryotes. Recently, it has been reported that the YTH domain conveys RNA-binding ability to a new class of proteins. However, the roles of most YTH family members lacking common sequence motifs outside the YTH domain are unknown. more...
