Riboregulation Of Bacterial Transposons, Michael J. Ellis
Riboregulation Of Bacterial Transposons, Michael J. Ellis
Electronic Thesis and Dissertation Repository
Bacterial transposons typically exist in a mutually beneficial relationship with the host cell. Limited transposition can benefit the host while also ensuring the survival of the element. An important component of this relationship is that transposition must be tightly regulated. In this thesis I explore ways that the host and transposon each control transposition in E. coli and provide evidence that a transposon can also control host gene expression in S. enterica Typhimurium. Post-transcriptional regulation with small non-coding RNAs (sRNA) has emerged as a key way that bacteria respond to stress and regulate many cellular processes. The RNA-binding protein Hfq …
