The Antimicrobial Peptide Database (APD) contains 2774 antimicrobial peptides from six kingdoms (278 bacteriocins from bacteria, 4 from archaea, 8 from protists, 13 from fungi, 339 from plants, and 2079 from animals) with the following activity:
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, 1021 active peptides from amphibians, 104 fish peptides, 22 reptile peptides, 38 from birds, 484 from arthropods, 145 from chelicerata, 50 from crustaceans, 7 from myriapods, 276 from insects, 43 from spiders, 72 from scorpions, 35 from molluscs; and more.

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.
