The p113 peptide's ability to selectively inhibit harmful bacteria while maintaining a healthy oral microbiome underscores its potential for revolutionizing how we approach dental hygiene and disease prevention.

Understanding the P113 Peptide

P113 is a short peptide composed of 12 amino acids, with the sequence AKRHHGYKRKFH. Its origin from histatin 5, a protein found in human saliva, highlights its inherent biocompatibility.Antimicrobial Peptide P-113-DPS Suppresses the ... Research indicates that p113 retains the crucial antibacterial and antifungal activities of its parent protein. Its mechanism of action often involves disrupting microbial cell membranes, leading to cell death. Unlike harsh chemical antiseptics, p113 demonstrates selectivity, targeting pathogenic microorganisms with minimal impact on beneficial oral flora. This selectivity is a key advantage for applications in oral health, where preserving the natural balance of the microbiome is essential.
