Differential Activation Of Dead Box Rna Helicases Rhlb And Rhle By Hfq/Srnas And Their Target Mrnas, Amit Kumar

Wayne State University Theses

Number of small RNA (sRNA) gene regulators have mounted in E. coli over the years whereas the number of validated protein partners has not changed considerably. Hfq has remained the only well studied global regulatory partner of sRNAs in E. coli. However, direct or indirect involvement of other protein partners has always been speculated. Study from Blasi lab has shown that CsdA, one of the five DEAD-box RNA helicases of E. coli, is required for the DsrA mediated upregulation of rpoS under cold stress condition. Previous study from our lab has identified two other DEAD-box RNA helicases, RhlB and RhlE, …
