Antimicrobial peptidesfunction Antimicrobial peptides (AMPs) represent a vital component of innate immunity across a vast array of organisms, from microbes to humans. These short amino acid sequences, typically ranging from 10 to 50 amino acids, exhibit potent activity against a broad spectrum of microorganisms, including bacteria, fungi, and viruses. Their unique mechanisms of action and ability to combat antimicrobial resistance make them a compelling alternative to conventional antibiotics. This article delves into a comprehensive antimicrobial peptides list, exploring their classification, sources, properties, and emerging applications, drawing upon extensive scientific research and databases.

Understanding Antimicrobial Peptides

At their core, antimicrobial peptides (AMPs) are effector molecules of the innate immune system. They are produced constitutively or are inducible by infectious and/or inflammatory stimuli, such as pro-inflammatory cytokines or bacterial molecules like lipopolysaccharides (LPS)作者：L Zhang·2016·被引用次数：1282—Properties and diversity of AMPs ·Bacillus polymyxa· vancomycin · Amycolatopsis · Pseudomonas aeruginosa · Klebsiella pneumoniae .... The expression of these peptides can be triggered by various factors, highlighting their dynamic role in host defense. Unlike traditional antibiotics, AMPs often act by disrupting microbial cell membranes, a mechanism that is generally harder for microbes to develop resistance against. This makes them particularly valuable in the face of rising antimicrobial resistance.

Diverse Sources and Classification of AMPs

The genesis of AMPs is remarkably diverse, with these peptides found in a wide array of organisms. They are produced by various organisms, and their discovery spans across different biological kingdoms.List of antimicrobial peptides. | Download Scientific Diagram For instance, Andropin from insects and Bombinin from amphibians are well-documented examples.Examples of antimicrobial peptides ;Andropin from insects. Bombinin from amphibians. Buforin II from amphibians. CAP18 from rabbits. Cepropins from insects In humans, defensins, cathelicidins, and histatins are prominent AMP families. Research into Amphibian antimicrobial peptides has revealed a rich source of potent molecules.

AMPs can be broadly classified based on their structure, amino acid composition, and chargeCategory:Antimicrobial peptides. Some common classifications include:

* Cationic peptides: Many AMPs carry a net positive charge at physiological pH, facilitating their interaction with negatively charged microbial membranes. Examples include magainin 2, lacticin Q, and arenicin, alongside cationic peptides like TC19, TC84, and BP2.

* Amphipathic peptides: These peptides possess both hydrophobic and hydrophilic regions, enabling them to insert into and disrupt lipid bilayers.

* Based on Structure:

* Cysteine-rich peptides: Many AMPs feature disulfide bonds that stabilize their structure. Peptides with 3 disulfide bonds include α-defensins from humans (HNP-1, HNP-2, cryptidins), rabbits (NP-1), and rats; β-defensins from humans, and disulphide bridge containing antimicrobial peptides such as HNP-3, mBD-8, phormicin, drosomycin, Ah-AMP-1, MGD-1, protegrin-1, and big defensin.

* Linear peptides: These lack disulfide bonds and often adopt helical structures.

* Based on Amino Acid Composition: Various AMPs are characterized by an abundance of specific amino acids, leading to categories like Trp-rich, His-rich, Pro-rich, Arg-rich, Gly-rich (classic), Leu-rich, Ser-rich, Lys-rich, Asp-rich, and Ala-rich AMPs.

Notable Antimicrobial Peptides and Databases

The scientific community has cataloged a vast number of AMPs, with dedicated databases serving as invaluable resources for researchersAntimicrobial Peptides | Suppliers & Custom Synthesis. The Antimicrobial Peptide Database (APD), particularly APD3, updated in September 2025, is a significant repository, currently including data on 5680 peptides, with 3351 being natural AMPs.
