What this research studies

Researchers will create and refine computer methods that combine quantum and molecular mechanics to simulate chemical reactions and movements inside biomolecules. They will apply these methods to a bacterial enzyme absent in humans (DXPS) and to how drugs form covalent bonds with serine β-lactamases, enzymes linked to antibiotic resistance. The work is entirely computational and focuses on capturing both electronic changes and large-scale motions to predict reaction energies and binding steps. Better simulations should make it easier for scientists to design new antibiotics and enzyme inhibitors.

Who could benefit from this research

Good fit: This grant does not enroll patients; its findings are intended to benefit people with antibiotic-resistant bacterial infections in the future.

Not a fit: People needing immediate treatment for an active infection will not get direct or immediate benefit because this is preclinical computational research.

Why it matters

Potential benefit: If successful, this work could speed up the design of better antibiotics and inhibitors to combat drug-resistant infections.

How similar studies have performed: Related QM/MM approaches exist and have shown promise for specific reactions, but applying them robustly to routine free-energy simulations and drug-binding steps is still novel and technically challenging.
