Bac2A; Bactenecin 2A

Bac2A is a linear antimicrobial peptide derived from bovine bactenecin, a cationic host defense peptide found in neutrophils. In Bac2A, the cysteine residues responsible for disulfide bond formation in native bactenecin are replaced with alanine, producing a linear structure while retaining potent antimicrobial activity. Bac2A exhibits broad-spectrum effects against Gram-positive and Gram-negative bacteria by interacting with microbial membranes. This peptide is widely used in innate immunity research, antimicrobial mechanism studies, membrane–peptide interaction analysis, and development of peptide-based anti-infective agents targeting resistant bacterial pathogens and host defense pathways.
