The Antimicrobial Peptide Database (APD) contains 2652 antimicrobial peptides from six kingdoms (264 bacteriocins from bacteria, 4 from archaea, 7 from protists, 13 from fungi, 323 from plants, and 2001 from animals) with the following activity:
This comprehensive AMP database resource is manually curated based on a set of data-collection criteria (see About).
Antiviral Peptides (Anti-HIV)
There are 112 human host defense peptides, 1007 active peptides from amphibians, 95 fish peptides, 18 reptile peptides, 38 from birds, 444 from arthropods, 134 from chelicerata, 41 from crustaceans, 6 from myriapods, 259 from insects, 42 from spiders, 65 from scorpions, 34 from molluscs; and more. A Universal Peptide Nomenclature; A Unified Peptide Classification
Of the 358 unique 3D structures annotated in the APD, 244 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. 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.
