Group Ii Intron Dynamics In Heterologous Hosts, Venkata Raghavendra Aditya Chalamcharla

Legacy Theses & Dissertations (2009 - 2024)

Group II introns are ribozymes with an innate ability to self-splice. They are found predominantly in bacterial and bacterial-derived organellar genomes, but not in the nuclear genomes of eukaryotes. In bacteria, group II introns often behave as mobile retroelements, invading host DNA and exploiting its machinery to complete the retromobility process. The object of my studies is the group II intron found in the Lactococcus lactis relaxase gene. To determine the nature of the group II intron-host relationship, we performed a genetic screen and identified several host factors that affect group II intron retromobility in Escherichia coli, which provides a …
