304:, protein folding, and cell wall synthesis. The initial contact between the peptide and the target organism is electrostatic, as most bacterial surfaces are anionic, or hydrophobic, such as in the antimicrobial peptide Piscidin. Their amino acid composition, amphipathicity, cationic charge and size allow them to attach to and insert into membrane bilayers to form pores by ‘barrel-stave’, ‘carpet’ or ‘toroidal-pore’ mechanisms. Alternately, they may penetrate into the cell to bind intracellular molecules which are crucial to cell living. Intracellular binding models includes inhibition of cell wall synthesis, alteration of the cytoplasmic membrane, activation of autolysin, inhibition of DNA, RNA, and protein synthesis, and inhibition of certain enzymes. In many cases, the exact mechanism of killing is not known. One emerging technique for the study of such mechanisms is 730: 104: 141:
residues aligned along one side and hydrophobic amino acid residues aligned along the opposite side of a helical molecule. This amphipathicity of the antimicrobial peptides allows them to partition into the membrane lipid bilayer. The ability to associate with membranes is a definitive feature of antimicrobial peptides, although membrane permeabilization is not necessary. These peptides have a variety of antimicrobial activities ranging from membrane permeabilization to action on a range of cytoplasmic targets.

AMPs have been observed having functions other than bacterial and fungal killing. These activities include antiviral effects, but also roles in host defence such as anticancer functions and roles in neurology. This has led to a movement for re-branding AMPs as "Host-defence peptides" to encompass the

The ‘Trojan Horse’ approach to solving this problem capitalizes on the innate need for iron by pathogens. “Smuggling” antimicrobials into the pathogen is accomplished by linking them to siderophores for transport.

Disordered toroidal-pore model: According to this model, the disordered AMPs wrap around the lipid bilayer and create a pore, which disrupts the membrane's integrity and leads to the death of the microbe. Unlike the toroidal model, which suggests that the AMP creates a stable toroidal structure, the

Carpet model: The carpet model proposes that AMPs adsorb onto the lipid bilayer of the microbial cell membrane, forming a dense layer that causes the membrane to become permeabilized.
