FIG. 2.

Bactericidal activities of (A and D) PBP 10, (B and E) LL37, and (C and F) mellitin (all squares) against gram-negative Escherichia coli SG13009 (A to C) and gram-positive Bacillus subtilis ATCC 6051 (D to F) by themselves and their inhibition in the presence of increasing concentrations of LPS (circles), LTA (open triangles), or PIP₂ (squares with dots). Other membrane phospholipids have limited or no effect (PS, filled triangles; PC, filled circles; BL, diamonds). The data shown are means ± standard deviations of three to five experiments.
