Characteristics of peptides with nine residues. (A) Scheme chemical structural formula and sequence of the designed peptides. (B) Circular dichroism spectrum of Peptides K1–K6. (C) Minimal inhibitory concentration (MIC) values of peptides and gentamicin against bacteria isolated from clinical infection were determined as described in Materials and Methods and shown in a color code for the dilution of a standard stock of the indicated peptide (1 to 64 μM) that showed complete growth inhibition.
