Characterization of the structure-function relationship of a novel salt-resistant antimicrobial peptide, RR12

Antimicrobial peptides (AMPs) are potential candidates in designing new anti-infective agents. However, many AMPs show poor bactericidal activities in physical salt and serum solutions. Here, we disclosed the structure-function relationships of a novel salt-resistant antimicrobial peptide, RR12, which could further explain its mode of action and show its applicability in developing new antibacterial agents.
