A novel CsrA titration mechanism regulates fimbrial gene expression in Salmonella typhimurium.

Abstract

A hierarchical control of fimbrial gene expression limits laboratory grown cultures of Salmonella enterica serovar typhimurium (S. typhimurium) to the production of type I fimbriae encoded by the fimAICDHF operon. Here we show that an unlikely culprit, namely the 5'-untranslated region (5'-UTR) of a messenger (m)RNA, coordinated the regulation. Binding of… (More)
