Polysaccharide release factors drive lipid-carrier recycling in bacteria

Henri Voedts, Ombeline Verstraete, Rodolphe Auger…·Jean‐François Collet

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.
