Crosslinking of peptidoglycan strands in cell-wall synthesis. Elongation of the glycan strand is carried out by PBPs with transglycosylase activity. The transpeptidation reaction, where the terminal d-Ala is displaced and the peptide stems are crosslinked is accomplished by PBPs such as PBP2a in MRSA.
