Signal-regulator interactions. Genetic analysis of the effector binding site of xylS, the benzoate-activated positive regulator of Pseudomonas TOL plasmid meta-cleavage pathway operon.

Abstract excerpt

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 pathway operon is specifically stimulated by the XylS protein positive regulator either through activation of this regulator by benzoate effectors or through its hyperproduction. One xylS mutant that exhibits constitutive expression of...
