Abstract: Antimicrobial peptides (AMPs) are natural antibiotics, synthesized by ribosomes, with an effect on the natural immunity of animal organisms. AMPs differ in composition [sequence and type of amino acids (AAs)] and structure, which contribute to rapid lysis and have a varied spectrum of antimicrobial activity. AMPs are: peptides (Pps) with alpha-helix structure (i.e., cecropins, magainins, mellitin, etc.); cyclic Pps and ring with several cysteine residues (i.e., defensins, protegrins, etc.); Pps rich in one or another AA (i.e., proline argininerich PR39, histidine, glycine, etc.). Most AMPs are characterized by hydrophobic and cationic properties, adopt an amphipathic structure (alpha-helix, spiral beta or alpha-helix / spiral beta), which is essential for antimicrobial activity.
