The Antimicrobial Peptide Database (APD) contains 2568 antimicrobial peptides (250 bacteriocins from bacteria, 2 from archaea, 7 from protists, 13 from fungi, 318 from plants, and 1938 from animals) with the following activity:
A comprehensive AMP database resource manually curated based on a set of data-collection criteria (see About).
Antiviral Peptides (Anti-HIV)
There are 111 human host defense peptides, 987 active peptides from amphibians, 91 fish peptides, 17 reptile peptides, 36 from birds, 423 from arthropods, 132 from chelicerata, 36 from crustaceans, 6 from myriapods, 250 from insects, 42 from spiders, 63 from scorpions, 32 from molluscs; and more.
Of the 345 unique 3D structures annotated in the APD, 233 with coordinates deposited in the Protein Data Bank (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.
