Characterization of library optimized syn-safencin variants. a Secondary structure predictions of peptide library hits. Hydrophobic, cationic, and anionic residues are orange, blue, or red, respectively. b Alignments of peptide library hits to the 25 residue syn-safencin parent peptide. Residue changes are highlighted in red. c MIC table of peptide library hits against a variety of organisms. Data are representative of three biological replicates (n = 3)
