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 …

The activity of the ς 54-promoter Pu of Pseudomonas putida was examined in vitro with a
DNA template lacking upstream activating sequences, such that RNA polymerase can be …

The sequence elements determining the binding of the σ 54-containing RNA polymerase (σ
54-RNAP) to the Pu promoter of Pseudomonas putida have been examined. Contrary to …

A truncated derivative of the XylR protein, which is able to constitutively activate the σ54-
dependentPupromoter of the TOL (toluene biodegradation) plasmid ofPseudomonas putida …

XylS, an AraC family protein, activates transcription from the benzoate degradation pathway
Pm promoter in the presence of a substrate effector such as 3-methylbenzoate (3MB). We …

We describe a mutation in rpoD, the gene encoding the σ 70 subunit of RNA polymerase,
which alters the promoter specificity of the holoenzyme in vivo. The mutant σ causes a …

In the presence of m-xylene, the Pu promoter of the TOL plasmid of Pseudomonas putida is
activated by the prokaryotic enhancer-binding protein XylR. The intervening DNA segment …

The interactions between the σ 54-containing RNA polymerase (σ 54-RNAP) and the region
of the Pseudomonas putida Pu promoter spanning from the enhancer to the binding site for …

Bacterial RNA polymerase and a “sigma” transcription factor form an initiation-competent
“open” complex at a promoter by disruption of about 14 base pairs. Strand separation is …

The Pseudomonas sp. strain ADP protein AtzR is a LysR‐type transcriptional regulator
required for activation of the atzDEF operon in response to nitrogen limitation and cyanuric …
