Figure 3. Cellular activity of AIP analogues. A) Activation dose–response curves for AIP-I (^) and analogues hb-Asp AIP-I (*), D5A hb-Ala AIP-I (~), and D5A b-Ala AIP-I (*). AIPs were added in increasing concentrations to an exponential phase culture of a group I S. aureus reporter strain (RN9222). Samples were removed after 60 min and assayed for b-lactamase activity by the <t>nitrocefin</t> method. Data are plotted as percent maximal activation, nor- malized for cell density, versus peptide concentration. Errors; SEM, n=3. B) Inhibition dose–response curves for D5A AIP (*) and analogues D5A hb- Ala AIP-I (~), D5A b-Ala AIP-I (*), Hcy AIP-I (^), Hcy AIP-III (&), and hb-Asp AIP-I (!). Group II reporter cells (RN9367) were treated with a fixed concen- tration of AIP-II (125 nm) and varying concentrations of the indicated ana- logues. b-lactamase activity was measured, and the normalized data are pre- sented as in panel A. The dose–response data for the D5A b-Ala AIP-I ana- logue do not fit an inhibition curve. Errors; SEM, n=3. Additional cellular activity data is provided in Figures S3–S5.

Figure 3. Cellular activity of AIP analogues. A) Activation dose–response curves for AIP-I (^) and analogues hb-Asp AIP-I (*), D5A hb-Ala AIP-I (~), and D5A b-Ala AIP-I (*). AIPs were added in increasing concentrations to an exponential phase culture of a group I S. aureus reporter strain (RN9222). Samples were removed after 60 min and assayed for b-lactamase activity by the nitrocefin method. Data are plotted as percent maximal activation, nor- malized for cell density, versus peptide concentration. Errors; SEM, n=3. B) Inhibition dose–response curves for D5A AIP (*) and analogues D5A hb- Ala AIP-I (~), D5A b-Ala AIP-I (*), Hcy AIP-I (^), Hcy AIP-III (&), and hb-Asp AIP-I (!). Group II reporter cells (RN9367) were treated with a fixed concen- tration of AIP-II (125 nm) and varying concentrations of the indicated ana- logues. b-lactamase activity was measured, and the normalized data are pre- sented as in panel A. The dose–response data for the D5A b-Ala AIP-I ana- logue do not fit an inhibition curve. Errors; SEM, n=3. Additional cellular activity data is provided in Figures S3–S5.
