A Summary of unmodified monomers and their anhydroMurNAc counterparts identified by PGFinder. For each muropeptide, the intensity and abundance of the AnhydroMurNAc modification are provided, alongside the retention time. The shift in retention time (ΔT (min)) and the presence of signature ions are indicated. B Example MS/MS spectrum showing the identified signature ions in red for a singly charged ([M + H]+) ion corresponding to the gm(Anh)-AEJA muropeptide. RT retention time.
