The synthesis of bacterial cell wall peptidoglycan was reconstituted in lipid bilayers and detected by a novel Förster resonance energy transfer real-time assay.

The universal bacteria cell wall component peptidoglycan impacts the egg-laying behavior of infected Drosophila females by directly modulating the activity of few brain octopaminergic neurons.

Enterococci faecium encodes unique peptidoglycan composition and remodeling activity that activates host immunity.

Female fruit flies sense bacteria-derived peptidoglycan via the octopaminergic neurons to adapt their egg laying behavior to their infection status.

Chi3l1 binds to bacterial peptidoglycan, helping anchor and organize bacteria within the mucus layer.

The Braun lipoprotein is tethered to peptidoglycan independently from the insertion of newly-synthesized peptidoglycan subunits into the expanding cell wall generating a dynamic equilibrium between free and bound protein forms.

Production of the L,D-transpeptidase YcbB and elevated synthesis of the (p)ppGpp alarmone reveals a new mode of peptidoglycan polymerization that bypasses the D,D-transpeptidase activity of PBPs and leads to broad-spectrum β-lactam resistance in Escherichia coli.

The protein CpoB regulates PBP1B activity in response to the Tol energy state, which facilitates feedback and synchronicity between envelope constriction processes during Gram-negative bacterial cell division.

A lytic transglycosylase connects bacterial focal adhesion complexes to the peptidoglycan cell wall and thus transmits proton motive force from the inner membrane to cell surface.

Allosteric mechanism of dual β-lactam binding in L,D-transpeptidase from Mycobacterium tuberculosis.
