An essential feature of bacterial plasmids is their ability to replicate as autonomous genetic
elements in a controlled way within the host. Therefore, they can be used to explore the …

Antisense RNA control is now recognized as an efficient and specific means of regulating
gene expression at the posttranscriptional level. Almost all naturally occurring cases have …

For a long time, RNA has been merely regarded as a molecule that can either function as a
messenger (mRNA) or as part of the translational machinery (tRNA, rRNA). Meanwhile, it …

Antisense RNA-mediated regulation is widespread in bacteria. Most antisense RNA control
systems have been found in plasmids, phages, and transposons. Fewer examples were …

Bacterial plasmids maintain their number of copies by negative regulatory systems that
adjust the rate of replication per plasmid copy in response to fluctuations in the copy …

The structure of the 45 amino acid transcriptional repressor, CopG, has been solved
unliganded and bound to its target operator DNA. The protein, encoded by the promiscuous …

The main features that characterize rolling‐circle replication (RCR)(see Fig. 1A) derive from
its singular initiation mechanism, which relies on the sequence‐specific cleavage, at the nick …

Transcription initiation of the copy-number control and better-than-random segregation
genes of the broad-host-range and low-copy-number plasmid pSM19035 are subjected to …

Rolling circle‐replicating plasmids constitute a group of small, promiscuous multicopy
replicons spread among eubacteria. Until recently, rolling circle replication seemed to be …

This paper reviews the present knowledge of the structure and properties of small (< 5 kb)
plasmids present in Lactobacillus spp. The data show that plasmids from Lactobacillus spp …
