BioStruct PhD project

Determinants of selectivity, action, and resistance of antibiotics binding to prokaryotic and eukaryotic ribosomes
Several classes of antibiotics specifically inhibit the activity of ribosomes by binding to the peptidyl transferase center (PTC) and the ribosomal exit tunnel region at adjacent or overlapping sites. Available high-resolution structures of antibiotics bound to ribosomal subunits provide crucial insights regarding the binding sites, binding modes, and mechanism of action for several antibiotics. This information creates possibilities to suggest chemical modifications to achieve higher binding affinity and selectivity of antibiotics or even new classes of anti-bacterial drugs. However, the structure elucidation only provides a static view of the binding processes, but does neither reveal the dynamics governing ribosomal function nor the energetic determinants of antibiotics binding. Molecular dynamics simulations (MD) in combination with free energy calculations are suitable to fill this gap. So far, neither the PTC nor the ribosomal exit tunnel have been investigated in complex with bound antibiotics by these techniques. The goal of this project is to investigate for the first time dynamical and energetic properties of antibiotic-ribosome complexes in atomic detail by MD in combination with free energy calculations. This provides a unique opportunity for a detailed analysis of antibiotics selectivity, action, and resistance in terms of energetics of binding, influences of structural components of more extended binding site regions, and resistance mechanisms resembling allosteric effects.
