Expression of the Pseudomonas putida TOL plasmid upper pathway operon requires a
promoter that belongs to the-12/-24 class. Stimulation of transcription from this promoter is …

Stimulation of transcription from the Pseudomonas TOL plasmid xylS gene promoter (Ps)
and the upperpathway operon promoter (Pu) is dependent on the positive regulator protein …

The xylR and xylS genes, which encode the positive regulators of the TOL plasmid catabolic
pathways, are adjacent genes on the TOL plasmid and are transcribed from divergent …

The physical and the functional organization of the upstreamcis-acting sequence that
controls at a distance the transcriptional activity ofPuandPs, the two σ54-dependent …

▪ Abstract The xyl genes of Pseudomonas putida TOL plasmid that specify catabolism of
toluene and xylenes are organized in four transcriptional units: the upper-operon …

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 …

In the presence of toluene and xylenes, the sigma 54-dependent Ps promoter of the TOL
(toluene biodegradation) plasmid pWW0 of Pseudomonas putida is activated at a distance …

The alkylbenzoate degradation genes of Pseudomonas putida TOL plasmid are positively
regulated by XylS, an AraC family protein, in a benzoate-dependent manner. In this study …

This study reports a genetic analysis of the interactions between a positive regulator of gene
expression and its effector molecules. Transcription of the TOL plasmid meta-cleavage …

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