The Antimicrobial Peptide Database (APD) contains 2814 antimicrobial peptides from six kingdoms (297 bacteriocins and peptide antibiotics from bacteria, 4 from archaea, 8 from protists, 13 from fungi, 343 from plants, and 2149 from animals) with the following activity (Total AMPs: 2891):
Antibacterial peptides; Antibiofilm peptides
This comprehensive database for antimicrobial peptides is manually curated based on a set of data-collection criteria (see About).
There are 122 human host defense peptides, 1038 active peptides from amphibians (974 from frogs), 113 fish peptides, 32 reptile peptides, 40 from birds, 500 from arthropods, 150 from chelicerata, 53 from crustaceans, 7 from myriapods, 284 from insects, 43 from spiders, 77 from scorpions, 36 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.
