The Antimicrobial Peptide Database (APD) contains 2445 antimicrobial peptides (243 bacteriocins from bacteria, 2 from archaea, and 2158 from eukaryota [7 from protists, 13 from fungi, 311 from plants, and 1828 from animals]) with the following activity:
Antibacterial Peptides
Antiviral Peptides
Antifungal Peptides
Antiparasitic Peptides
Anticancer Peptides
Anti-protist Peptides
Insecticidal Peptides
Spermicidal Peptides
Anti-HIV Peptides
Chemotactic peptides
Antioxidant peptides
Protease inhibitors
A comprehensive AMP database resource manually curated based on a set of data-collection criteria (see About).
There are 106 human host defense peptides, 946 active peptides from amphibians, 80 fish AMPs, 14 reptile AMPs, 36 from birds, 230 from insects (e.g. lucifensin), 33 from spiders, 36 from crustaceans, and more.

Of the 326 unique 3D structures annotated in the APD, 216 with coordinates deposited in the PDB can be rotated, zoomed, and viewed.Top left: Amphibian magainin II;Top right: bovine lactoferricin;Bottom left: plant PsD1;Bottom right: bovine indolicidin.

This database consists of a pipeline of search functions. 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.
In addition, you can access the APD Peptide Calculator here.
