James Alexander Booth’s project group:
Bacterial type I toxin-antitoxin systems
Toxin-antitoxin (TA) systems are present in bacterial genomes and on mobile genetic elements. These systems serve diverse functions, ranging from plasmid maintenance to the inhibition of phage infection. Our focus is on type I systems, where the antitoxin is a small RNA (sRNA) molecule that interferes with the translation of the toxin transcript. Our research spans from understanding the RNA dynamics leading to toxin translation to examining the mechanisms of action of the toxins, as well as comprehending the biological functions of these systems. Additionally, we translate our insights into the origins of toxin toxicity to produce synthetic antimicrobial peptides (AMPs) in an effort to address antimicrobial resistance (AMR). Our work on synthetic AMP development encompasses a multitude of in vitro assays to assess their efficacy, toxicity and synergy with clinically approved antibiotics.
The techniques we utilize in our projects above allow us to feely modify the genomes of microbes. One potentially important organism in the transition to a low carbon society is Cupriavidus Necator, as it fixes carbon dioxide (CO2) to produce more complex carbon based chemicals. We carry out research on C. Necator and attempt to produce useful chemicals from waste carbon dioxide.
