Though an essential trace element, manganese is generally accorded little importance in
biology other than as a cofactor for some free radical detoxifying enzymes and in the …

Adaptation to the changing environment requires both the integration of external signals and
the co‐ordination of internal responses. Around 50 non‐coding small RNAs (sRNAs) have …

RyhB is a small antisense regulatory RNA that is repressed by the Fur repressor and
negatively regulates at least six mRNAs encoding Fe-binding or Fe-storage proteins in …

Small RNA (sRNA) molecules have gained much interest lately, as recent genome‐wide
studies have shown that they are widespread in a variety of organisms. The relatively small …

The bacterial transcriptome is a dynamic entity that reflects the organism's immediate,
ongoing and genome‐wide response to its environment. Microarray expression profiling …

Small RNAs can act to regulate both the synthesis of proteins, by affecting mRNA
transcription, translation and stability, and the activity of specific proteins by binding to them …

DsrA RNA regulates the translation of two global regulatory proteins in Escherichia coli.
DsrA activates the translation of RpoS while repressing the translation of H-NS. The RNA …

Regulation of the σ factor RpoS occurs at the levels of transcription, translation, and protein
stability activity, and it determines whether Escherichia coli turns on or off the stationary …

General inspection of a role performed in the cell by RNAs allows us to distinguish three
major groups of transcripts: I. protein-coding mRNAs, II. non-coding housekeeping and III …

Enteric pathogens such as Salmonella enterica and Escherichia coli face the daunting task
of surviving passage through the extremely acid pH of the stomach in order to establish an …
