Emerging models of the bacterial nucleoid show that nucleoid-associated proteins (NAPs)
and transcription contribute in combination to the dynamic nature of nucleoid structure …

This review presents a comparison between the complex genetic regulatory networks that
control nitrogen fixation in three representative rhizobial species, Rhizobium meliloti …

How enhancers are able to activate promoters located several kilobases away is unknown.
Activation by the wing margin enhancer in the cut gene, located 85 kb from the promoter …

The early notion of DNA as a passive target for regulatory proteins has given way to the
realization that higher-order DNA structures and DNA-protein complexes are at the basis of …

PII proteins, found in Bacteria, Archaea and plants, help coordinate carbon and nitrogen
assimilation by regulating the activity of signal transduction enzymes in response to diverse …

Synthesis of most anaerobic respiratory pathways is subject to dual regulation by
anaerobiosis and nitrate. Anaerobic induction is mediated by the FNR protein. Dual …

The NIFL regulatory protein controls transcriptional activation of nitrogen fixation (nif) genes
in Azotobacter vinelandii by direct interaction with the enhancer binding protein NIFA …

▪ Abstract This review attempts to substantiate the notion that nonlinear DNA structures allow
prokaryotic cells to evolve complex signal integration devices that, to some extent, parallel …

Transcriptional activation of many developmentally regulated genes is mediated by proteins
binding to enhancer sequences located several kilobases from the promoter. Existing …

To activate transcription of the glnA gene, the dimeric NTRC protein (nitrogen regulatory
protein C) of enteric bacteria binds to an enhancer located approximately 100 bp upstream …
