Fig. 4. Accumulation of UDP-MurNAc-pentapeptide in E. faecium E980 treated with P8-d-(S6R, R15A)-C10 or P8-l-(S6R, R15A)-C10 lipopeptides. Vancomycin used as a positive control. Identity of the UDP-MurNAc-PP peak confirmed by LCMS and by comparison with pure reference material. Data based on triplicate measurements.
