TranscriptomicsGene expression profiling of constitutively competent comR and proQ mutants and RNase R (rnr) mutant of L. pneumophila
Bacterial competence is a genetically programmed process that is triggered as a response to environmental stimuli. DNA uptake from the extracellular milieu by competence requires the expression of a complex machinery composed of a competence pseudopilus and a DNA translocase. In L. pneumophila, it ...

GenomicsGenome-wide distribution of RNA-DNA hybrids identifies RNase H targets in tRNA genes, retrotransposons and mitochondria
During transcription the nascent RNA can invade the DNA template, forming extended RNA-DNA duplexes (R-loops). Here we employ ChIP-seq in strains expressing or lacking RNase H to map targets of RNase H activity throughout budding yeast genome. In wild-type strains, R-loops were readily detected over...

ProteomicsRNase R is associated in a functional complex with the RhpA DEAD-box RNA helicase in Helicobacter pylori
Ribonucleases are central players in post-transcriptional regulation, a major level of gene expression regulation in all cells. Here, we characterized the 3’-5’ exoribonuclease RNase R from the bacterial pathogen Helicobacter pylori. The "prototypical" Escherichia coli RNase R displays both exoribon...

ProteomicsAnalysis of RNA-dependent proteins in the cyanobacterium Synechocystis by RNase sensitive gradient profiling (Grad-R) Analysis of RNA-dependent proteins in the cyanobacterium Synechocystis by RNase sensitive gradient profiling (Grad-R)
RNA-binding proteins (RBPs) are an essential component of ribonucleoprotein complexes and are crucial for post-transcriptional regulation by regulatory sRNAs. Well-studied examples in different groups of bacteria include RBPs such as various ribosomal and RRM-domain containing proteins, or the RNA c...

TranscriptomicsStructural basis of ribosomal 30S subunit degradation by RNase R
Protein synthesis is a major energy-consuming process of the cell, which requires controlled production and turnover of ribosomes. While the last years have seen major advances in our understanding of ribosome biogenesis, structural insight into the degradation of ribosomes has been lacking. Here we...

TranscriptomicsIntroducing synthetic thermostable RNase inhibitors in single-cell RNA-seq
Single-cell RNA-sequencing (scRNAseq) is revolutionizing biomedicine, propelled by advances in methodology, ease of use, and cost reduction of library preparation. Over the past decade, there have been remarkable technical improvements in most aspects of single-cell transcriptomics. Yet, there has b...
