Table 2 Summary of the peaks shown in Fig. 12 and the reduced muropeptides in HPLC fractions obtained from E. coli D456 peptidoglycan treated with either Bd0468 or Bd3279 detected by LTQ-FT MS1.

From: Interrupting peptidoglycan deacetylation during Bdellovibrio predator-prey interaction prevents ultimate destruction of prey wall, liberating bacterial-ghosts
