Figure 1

Binding of cationic cytochrome c (cyt c) by S. aureus Sa113 wild type, gra RS mutant, and complemented gra RS mutant (A) and by the dlt A mutant and the dlt A/ gra RS double mutant (B). Bacteria were incubated with 500 μl cytochrome c solution (0.5 mg/ml) (A) or 750 μl cytochrome c solution (1 mg/ml) (B). The means and SEM of at least three independent experiments are shown. P values < 0.05 as calculated by Student's t test were regarded statistically significant.
