The muropeptide compositions of isogenic vancomycin-resistant and -susceptible Enterococcus faecalis strains were analyzed by reverse-phase high-performance liquid chromatography combined with amino acid analysis and fast atom bombardment mass spectrometry. Peptidoglycan of the susceptible strain contained pentapeptides as stem peptides, whereas peptidoglycan of the isogenic resistant strain was composed of muropeptides with tetrapeptide stem peptides. Despite the synthesis of lactate-terminating peptidoglycan precursors, no lactate-containing muropeptides were detected in peptidoglycan of the resistant strain. These findings indicate that either lactate-terminating precursors are not incorporated into peptidoglycan of the resistant strain or that the lactate residues are removed from peptidoglycan during synthesis.
