The Antimicrobial Peptide Database (APD) contains 2814 antimicrobial peptides from six kingdoms (286 bacteriocins and peptide antibiotics from bacteria, 4 from archaea, 8 from protists, 13 from fungi, 341 from plants, and 2108 from animals) with the following activity:
Antibacterial Peptides (Antibiofilms)
Antiviral Peptides (Anti-HIV)
Antifungal Peptides
Antiparasitic Peptides (Antimalaria)
Anticancer Peptides
Anti-protist Peptides
Insecticidal Peptides
Spermicidal Peptides
Chemotactic peptides
wound healing
Antioxidant peptides
Protease inhibitors
This comprehensive database for antimicrobial peptides is manually curated based on a set of data-collection criteria (see About). There are 116 human host defense peptides, 1022 active peptides from amphibians, 109 fish peptides, 32 reptile peptides, 38 from birds, 490 from arthropods, 150 from chelicerata, 52 from crustaceans, 7 from myriapods, 277 from insects, 43 from spiders, 72 from scorpions, 36 from molluscs; and more.

Of the 379 unique 3D structures annotated for host defense peptides in the APD, 270 with coordinates deposited in the Protein Data Bank (PDB) can be directly rotated, zoomed, and viewed.

This original database consists of a pipeline of search functions for innate immune peptides. You can search for peptide information using APD ID, peptide name, amino acid sequence, peptide motif, chemical modification, length, charge, hydrophobic content, PDB ID, 3D structure, methods for structural determination, peptide source organism, peptide family name, life domain/kingdom (bacteria, archaea, protists, fungi, plants, animals), biological activity (see the links above), synergistic effects, target microbes, molecular targets, mechanism of action, contributing authors, and year of publication.
