Chris Thomas @chrismthomas.bsky.social · 03/11/2025After discussion with some current students at the University of Birmingham I sent them a link to a YouTube video some of my students (Carys Ladd, Sanem Sertug and Yuqian Ye) made about our work a few years ago so I thought I would share the link: www.youtube.com/watch?v=yH8A... 000
Chris Thomas @chrismthomas.bsky.social · 12/05/2025Chris Thomas Our commercialisation arm, University of Birmingham Enterprise Ltd, issued a press release last week (bit.ly/3SBfuLq) related to our recent Nucleic Acids Research paper (bit.ly/4lSyCSH ) and other on-going work.bit.lyResearch advances on ‘displacing’ antibiotic resistance gene from bacteria - University of BirminghamThe research is on plasmids, small, circular strands of DNA, that allow bacteria to share genes rapidly, and carry genes conferring antibiotic resistance. 030

Chris Thomas @chrismthomas.bsky.social · 04/04/2025The second great paper concerns the discovery in Eva Top's group that an enigmatic protein encoded by IncP-1beta plasmids modulates the IncP-1 circuitry in E. coli to make the plasmid a burden in this host: Elg et al recently accepted in Molecular Biology and Evolution doi.org/10.1093/molb...doi.orgpendingpublicationsPending Publication 0105
Chris Thomas @chrismthomas.bsky.social · 04/04/2025It is a privilege to be an author on two great plasmid papers already this year. The first was McLean et al in Nature Microbiology focused on KorB and the discovery that it is a CTPase by Yung Le's group at the John Innes Institute in Norwich. www.nature.com/articles/s41...nature.comKorB switching from DNA-sliding clamp to repressor mediates long-range gene silencing in a multi-drug resistance plasmid - Nature MicrobiologyStructural and single-molecule analyses show the CTPase, KorB, is a sliding DNA clamp that interacts with a clamp-locking protein KorA to inhibit gene expression over distances of more than 1 kb in th... 1114
