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.

The paper identifies OutB, an inner membrane protein in Dickeya dadantii, as covalently attached to peptidoglycan, similar to Braun lipoprotein, and shows that Ldt03 and Ldt84 enzymes mediate this attachment through amide bond formation.
