We explore ways to combat drug resistance in pathogens and cancer

Superbugs are bacteria that cause disease and are resistant to all or many drugs. In one case in January 2017, a US woman died from a superbug infection that had spread throughout her system and could fend off 26 different antibiotics. GRIDD ECR Leader Dr Maria Halili and GRIDD Affiliate Professor Jennifer Martin and their research team are investigating an innovative approach: the discovery of drugs that disarm superbugs rather than killing them.


A structural biologist, Professor Martin and her team focused on understanding the actions of a key bacterial protein, DsbA, which makes up part of the ‘weapons assembly machinery’ in many harmful bacteria. Together with collaborators, her team is discovering which molecules inhibit or stop this machinery with the aim of developing these molecules into new and better antibacterials.The work stems from a seminal paper Professor Martin published 24 years ago that described the atomic resolution three-dimensional structure of this bacterial protein—a protein that turned out to be a master virulence regulator.
