Typas Lab @typaslab.bsky.social · 20/08/2026Among many additions since the preprint: a divergent DFG-like (DPV) motif that likely locks T7K in the ON mode, and the discovery of T7K homologues in jumbophages. 120
Typas Lab @typaslab.bsky.social · 20/08/2026This function was missed for ~50y b/c T7 biology was mainly explored in lab strains w/ few defenses. Our infection assays in natural isolates show strong phenotypes for T7K; it allows T7 to infect strains that carry diverse systems but share no common one, through a brute-force deactivation strategy 132
Typas Lab @typaslab.bsky.social · 20/08/2026Mechanistically, T7K’s C-terminal DNA-binding domain steers this activity towards DNA/RNA-binding proteins (building blocks of most defense systems). We map phosphorylation of Retron-Eco9 by T7K at critical residues; single phosphomimetic mutations at these T7K-modified sites abolish defense. 110
Typas Lab @typaslab.bsky.social · 20/08/2026Most known phage anti-defenses proteins block a single system. T7K is different: a hyper-promiscuous, dual-specificity kinase that phosphorylates nearly all host proteins in a short, early burst in infection, with no clear sequence motif. 110
Typas Lab @typaslab.bsky.social · 29/06/2026How can we harness the vast functional diversity of microbes on our planet? Join us at EMBL Heidelberg from 8–10 December 2026 to hear about ongoing efforts to decode gene function and organisation in human gut microbes, and to present your own research. www.embl.org/about/info/c... 23934
Typas Lab @typaslab.bsky.social · 29/04/2026We found that E. coli can be a key driver of selection for a high-fitness antibiotic resistant K. pneumoniae strain in complex communities. Higher-order interactions with other community members could enhance or decrease the selective advantage of the resistant mutant. 141
Typas Lab @typaslab.bsky.social · 29/04/2026We introduce a high-throughput method to quantify resistance-associated fitness costs inside complex gut microbiomes. This lets us identify which microbiota are permissive or restrictive for antibiotic-resistant pathogens. 121
Typas Lab @typaslab.bsky.social · 13/10/2025Excited to share our preprint led by Carlos Voogdt et al We developed new genetic tools & genome-wide libraries for species of the Bacteroidales order; constructed saturated barcoded transposon libraries in key representatives of three genera. www.biorxiv.org/content/10.1... 28645
Typas Lab @typaslab.bsky.social · 23/06/2025Excited for New Approaches and Concepts in Microbiology 2025 with sessions on Bacterial systems biology, Bacterial cell biology & protein machines, Microbiomes, Environment & evolution, Pathogenesis & phage, Antibiotic discovery, mechanisms, and resistance. #EESMicrobiology 15617
