Proteins induced in Escherichia coli by benzoic acid.

abstract：:The TspO outer membrane protein of Rhodobacter sphaeroides has been shown to be involved in controlling the transcription of a number of genes which encode enzymes involved in photopigment biosynthesis and the puc operon. The display of regulated genes appears identical to those genes encompassing the PpsR/AppA repres...

abstract：:Transposition is a DNA reorganization reaction potentially deleterious for the host. The frequency of transposition is limited by the amount of transposase. Therefore, strict regulation of a transposase is required to keep control over the destructive multiplication of the mobile element. We have shown previously that...

Mutants in rpoS arise in bacterial populations in the absence of stress, probably as a consequence of a subtle balance between self-preservation and nutritional competence. We characterized here one natural rpoS mu...
