The events that take place at the prokaryotic enhancer of the Pu promoter of Pseudomonas
putida prior to the engagement of the σ 54-RNA polymerase (σ 54-RNAP) have been …

Integration host factor (IHF) sites are largely absent from intergenic regions of ORFs
encoding central metabolic functions in Pseudomonas putida mt‐2. To gain an insight into …

The connection between the physiological control of the ς54-dependent Pu promoter of the
TOL plasmid pWW0 of Pseudomonas putida and the stringent response mediated by the …

Recognition of bacterial promoters is regulated by two distinct classes of sequence-specific
sigma factors, σ70 or σ54, that differ both in their primary sequence and in the requirement of …

The structural properties of the DNA molecule are known to play a critical role in
transcription. In this paper, the structural profiles of promoter regions were studied within the …

The xylR and xylS genes are divergent and control transcription of the TOL plasmid
catabolic pathways for toluene metabolism. Four promoters are found in the 300-bp …

The upper pathway operon of the Pseudomonas putida TOL plasmid belongs to the− 12/-24
class of promoters. These promoters exhibit three regions critical for regulated transcription …

Transpositional activity of mobile elements is not constant. Conditional regulation of host
factors involved in transposition may severely change the activity of mobile elements. We …

Transcriptional activation of σ54-RNA polymerase holoenzyme (σ54-RNAP) in bacteria is
dependent on a cis-acting DNA element (bacterial enhancer), which recruits the bacterial …

Atomic force microscopy (AFM) was used to analyze DNA bending induced by integration
host factor (IHF). The direct AFM visualization of IHF–DNA complexes on the OP1 promoter …
