Extended Data Fig. 9. The L,D transpeptidase ldt2 is required for covalent attachment of BbpA and BbpB to PG.

Extended Data Fig. 9

XIC analysis was performed on PG that was extracted from WT and Δldt mutant strains and analyzed by MS/MS. XIC’s of precursor masses (m/z) corresponding to PG-bound BbpA (AEmGGPDYVPAPS, m/z = 906.909, z = 2), ala-BbpA (AEmAGGPDYVPAPS, m/z = 942.427, z = 2), and BbpB (AEmGGPDIPM, m/z = 769.843, z = 2) are shown.
