(Tyr5.12,Lys7)-Polyphemusin II is a modified antimicrobial peptide with tyrosine substitutions at positions 5 and 12, enhancing hydrophobicity and charge distribution. The lysine at position 7 influences the peptide's ability to interact with microbial membranes. Researchers use it in studies on immune modulation and peptide-driven microbial defense mechanisms.
