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

Bacterial enhancer binding proteins (bEBPs) are transcriptional activators that assemble as
hexameric rings in their active forms and utilize ATP hydrolysis to remodel the conformation …

The PII family of signal transduction proteins are among the most widely distributed signal
proteins in the bacterial world. First identified in 1969 as a component of the glutamine …

Because of theirability to stimulate gene expression from distant sites and regardless of their
orientation, transcriptional enhancer elements are a puzzling class of regulatory DNA …

Transcription from the Klebsiella pneumoniae and Rhizobium meliloti nifH promoters
requires the positive control protein NifA and the alternative sigma factor σ 54, encoded by …

Understanding how Nature accomplishes the reduction of inert nitrogen gas to form
metabolically tractable ammonia at ambient temperature and pressure has challenged …

The ability of bacteria to respond to a multitude of environmental signals and integrate these
signals to trigger adaptive responses provides a successful strategy for survival in rapidly …

NAC (NAM, ATAF1, 2, and CUC2) transcription factors are one of the largest transcription
factor families found in the plants and are involved in diverse developmental and signalling …

A new bacterial promoter type has been identified in the last few years. Originally
designated as nif (= ni trogen f ixation) or ntr (= nit rogen r egulation) consensus promoter, it …
