Visualizing response to DNA damage in bacteria

The basis of this thesis has been the curiosity, however modest, to understand how DNA replication happens in vivo, particularly during the onset of DNA damage and beyond. DNA damage is a recurring phenomenon, which a (bacterial) cell faces in its lifetime from the environment or even its inherent metabolism. While we understand much about...

What is all this fuss about Tus?: Comparison of recent findings from biophysical and biochemical experiments

Synchronizing the convergence of the two-oppositely moving DNA replication machineries at specific termination sites is a tightly coordinated process in bacteria. In Escherichia coli, a “replication fork trap” – found within a chromosomal region where forks are allowed to enter but not leave – is set by the protein–DNA roadblock Tus–Ter. The...
