The paper identifies three periplasmic enzymes in E. coli that release polysaccharide cargo from the lipid carrier undecaprenyl, revealing a mechanism for bacterial envelope biogenesis and potential antibiotic targets.

This study shows Sphingobium yanoikuyae exhibits extreme envelope plasticity, switching growth morphologies at different temperatures through changes in outer membrane and peptidoglycan structure.

The paper identifies a stress-induced membrane insertion mechanism that activates the BepA metalloprotease by displacing its autoinhibitory plug, linking membrane association to protease function.

The paper introduces Cystector, a genetically encoded biosensor for cysteine that works across different organisms and monitors cysteine dynamics in live cells.

This study identifies the C-terminal domain (CTD) of BSAP-1 as the receptor-binding region, showing its role in specificity and potential for developing new tools.

This study investigates the structural and functional properties of LppB in Salmonella, showing it modulates outer membrane-peptidoglycan tethering by forming dimers and heterotrimers with Lpp, reducing crosslinking efficiency.

The paper identifies new protein-coding sequences in E. coli using transposon mutagenesis and translation reporters, revealing previously unannotated genes.

This study introduces a method combining plasma prefractionation and DIA to improve proteome coverage and depth, enabling robust biomarker identification in a COVID-19 cohort.
