PAF26 – Antimicrobial Peptides – AMP

PAF26 is a cell penetrating antimicrobial peptide (CP-AMP) with strong activity against fungi that cause postharvest decay in fruits, such as strains of Penicillium italicum, Penicillium digitatum, and Botrytis cinerea and is also active against Fusarium oxysporum. PAF26 has reduced toxicity to Escherichia coli and Saccharomyces cerevisiae, demonstrating selectivity towards certain filamentous fungi. PAF26 is endocytically internalized at low fungicidal concentrations and accumulates in vacuoles before being actively transported into the cytoplasm where it exerts its antifungal activity. PAF26 is not lytic or cytotoxic to human cells.
