Novel mechanistic insight into antibiotic resistance
Antibiotic-resistant bacteria are a growing health concern worldwide with many healthcare implications. Emerging evidence indicates that dormant bacteria subpopulations which are difficult to eradicate with conventional means are the primary source of antibiotic resistance. The EU-funded DiStRes project is investigating the RelA/SpoT (RSH) proteins that promote the stringent response in bacteria and modulate cell metabolism through the (p)ppGpp. Through a combined microbiology and structural biology approach, researchers will focus on the molecular mechanisms of ppGpp synthesis and hydrolysis. DiStRes will not only shed light on the mechanism of drug resistance, but also help design and screen novel drug candidates that target the stringent response in persistent bacteria.
