RNA polymerase-associated factors can significantly affect its performance at specific promoters. Here we identified a Pseudomonas putida RNA polymerases-associated protein as a homolog of Escherichia coli RapA. We found that P. putida RapA stimulate

The sigma(54)-factor controls expression of a variety of genes in response to environmental cues. Much previous work has implicated the nucleotide alarmone ppGpp and its co-factor DksA in control of sigma(54)-dependent transcription in the gut commen

Comparatively little is known about directed motility of environmental bacteria to common aromatic pollutants. Here, by expressing different parts of a (methyl)phenol-degradative pathway and the use of specific mutants, we show that taxis of Pseudomo

The bacterial nutritional and stress alarmone ppGpp and its co-factor DksA directly bind RNA polymerase to regulate its activity at certain σ70-dependent promoters. A number of promoters that are dependent on alternative σ-factors function poorly i

The RNA polymerase-binding protein DksA is a cofactor required for guanosine tetraphosphate (ppGpp)-responsive control of transcription from sigma70 promoters. Here we present evidence: (i) that both DksA and ppGpp are required for in vivo sigma54 tr

Some promoters, including the DmpR-controlled sigma(N)-dependent Po promoter, are effectively rendered silent in cells lacking the nutritional alarmone (p)ppGpp. Here we demonstrate that four mutations within the housekeeping sigma(D)-factor can rest

The Pseudomonas derived ς 54 -dependent regulators DmpR and XylR control the expression of genes involved in catabolism of aromatic compounds. Binding to distinct, nonoverlapping groups of aromatic effectors controls the activities of these transcri

The N-terminal domain, containing the 49 N-terminal amino-acid residues, of human extracellular superoxide dismutase (hEC-SOD) has been studied after construction of fusion proteins comprised of the defined domain and human carbonic anhydrase 11 (HCA

The Pr promoter is the first verified member of a class of bacterial σ(70)-promoters that only possess a single match to consensus within its -10 element. In its native context, the activity of this promoter determines the ability of Pseudomonas put

The activities of promoters can be temporally and conditionally regulated by mechanisms other than classical DNA-binding repressors and activators. One example is the inherently weak σ(70)-dependent Pr promoter that ultimately controls catabolism of
