Abstract
Antimicrobial activity and self-assembly of the modified TK913 peptide are described. We designed the peptides TK9Z1-4 and TKZ2-3 based on the TK913 sequence and prepared these peptides by Fmoc-SPPS. TKZ3 shows morphology change in the different concentration and potent antimicrobial activities. In addition, TKZ3 has stability in trypsin treatment.
