The PlyC-mediated lysis of sacculi purified from S. mutans strains. The lysis was monitored after 10, 20, 30, 40, 50 and 60 min as a decrease in OD₆₀₀. Results are presented as a fold change in OD₆₀₀ of the sacculi incubated with PlyC vs. the sacculi incubated without PlyC. Data points and error bars represent mean values of four biological replicates and standard deviation, respectively. P-values were determined by two-way ANOVA with Dunnett’s multiple comparisons test.
