NOV 2024 NEW ARTICLE FOR TOM ARROWSMITH AND BEN USHER
Our wonderful collaborators Drs Pierre Genevaux and Xibing Xu have a new Nature Communications paper, showing that MenT toxins are active in free-growing M. tuberculosis. This is a huge change to the accepted dogma of toxin-antitoxin systems, implying many might have physiological roles that have not yet been characterised. Congrats to Tom and Ben who are named authors on the paper.
SEP 2024 NEW ARTICLE FOR TOM ARROWSMITH
Congratulations to Tom Arrowsmith on a great new Nature Communications paper, showing that MenT toxins have variable routes to inhibition, and uncovering a mechanism for antitoxin-induced auto-phosphorylation of the toxin. This study continues our ongoing work into M. tuberculosis toxins in collabortion with Dr Pierre Genevaux (Université Toulouse III - Paul Sabatier, France) and this time includes molecular dynamics from Dr Agnieszka Bronowska (Newcastle University, UK). Also includes new structural data from lab alumnus Dr Ben Usher. Thanks and congratulations to everyone involved on a lovely result!
AUG 2024 NEW ARTICLE FOR SAM WENT
Congratulations to Sam Went on a super new Nature Communications paper, showing the structure of the PglX methyltransferase and how it can be rationally engineered to target new DNA sequences. These data demonstrate that PglX is the specificity factor for BREX methylation and defence. This work continues Salmonella investigations started by Dr David Picton with the wonderful Prof Jay Hinton at University of Liverpool, and was only possible through welcome collaborative inputs from Prof Darren Smith at Northumbria University, Dr Rick Morgan at New England Biolabs, Dr Giusy Mariano at the University of Surrey and Dr David Dryden.
JUL 2024 NEW NATURE PAPER
Exciting milestone congratulations to Sam Went and Ben Usher who are co-authors on a glorious new Nature paper from long-time collaborators Nils Birkholz and Peter Fineran at the University of Otago, New Zealand. It turns out some HTH proteins can bind both DNA and RNA, an effect likely more widespread than previously understood!
