Differential Modes of Peptide Binding onto Replicative Sliding Clamps from Various Bacterial Origins

Bacterial sliding clamps are molecular hubs that interact with many proteins involved in DNA metabolism through their binding, via a conserved peptidic sequence, into a universally conserved pocket. This interacting pocket is acknowledged as a potential molecular target for the development of new antibiotics. We previously designed short peptides with an improved affinity for the Escherichia coli binding pocket. Here we show that these peptides...
