Contribution Of The Novel C-Terminal Domain To The Ribosome Binding Activities Of Virulence Regulator Bipa, Heeren Makanji

Honors Scholar Theses

Bacterial GTPases regulate many cell functions, including the stress response, signal recognition, protein synthesis, and cell differentiation, through a molecular switch that is activated and deactivated depending on their nucleotide bound state (1). A member of the translational family of bacterial GTPases along with LepA and EF-G, BipA is a 67 kD protein that is essential for virulence and the stress response. Crystal structures from the Robinson lab have shown a unique C-terminal domain on BipA that has been implicated in ribosome binding. Using N-terminal deletion constructs, we have shown that the C-terminal domain is necessary, but not sufficient, to ...
