In the last decade regulatory RNAs have emerged as powerful tools to regulate the expression of genes both in prokaryotes and in eukaryotes. RNases, by degrading these RNA molecules, control the right amount of regulatory RNAs, which is fundamental for an accurate regulation of gene expression in the cell. Remarkably the first antisense RNAs identified were plasmid-encoded and their detailed study...
Conjugation of the E. faecalis plasmid pCF10 is triggered in response to peptide sex pheromone cCF10 produced by potential recipients. Regulation of this response is complex and multi-layered and includes a small regulatory RNA, Anti-Q that participates in a termination/antitermination decision controlling transcription of the conjugation structural genes. In this study, the secondary structure of...
