PsrA is a positive transcriptional regulator of the type III secretion system in Pseudomonas aeruginosa.

Infection and immunity - 1 Feb 2006

Shen D K, Filopon D, Kuhn L, Polack B, Toussaint B

Abstract excerpt

The type III secretion system (TTSS) of Pseudomonas aeruginosa is induced in vivo upon contact with eukaryotic cells and in vitro by calcium depletion in culture medium. We have observed a previously identified protein, PsrA, necessary for full activation of TTSS gene expression in P. aeruginosa. Electrophoretic mobility shift assays showed that recombinant PsrA could bind to the exsCEBA promoter region. A mutant...
