From: Muropeptides Stimulate Growth Resumption from Stationary Phase in Escherichia coli
Sugar – peptide bond is crucial for the MP growth resumption stimulation activity. Different MP variants were purified and tested in a growth resumption assay. Structures with intact sugar-peptide bonds can stimulate growth resumption, but NAM and its tripeptide together as separate molecules cannot. The average of three independent biological replicates is shown, error bars indicate standard error of the mean.
