MarT activates expression of the MisL autotransporter protein of Salmonella enterica serotype Typhimurium

J Bacteriol. 2007 May;189(10):3922-6. doi: 10.1128/JB.01746-06. Epub 2007 Mar 9.

Abstract

MisL is a Salmonella enterica serotype Typhimurium fibronectin binding protein whose expression is induced during infection of mice. T-POP transposon mutagenesis identified marT as a positive regulatory element controlling expression of a misL::lacZYA transcriptional fusion. Gel shift analysis identified MarT as a transcriptional activator of the misL promoter.
