APD3 - Antimicrobial Peptide Database

Antimicrobial Peptide Database (APD) is a database system dedicated to discovery timeline, glossary, nomenclature, classification, structure, function, information search, prediction, design, statistics and tools of AMPs. The peptide data stored in this original database were gleaned from the literature. Among the natural AMPs with know antimicrobial activity, there are human host defense peptides, from mammals annotated, active peptides from amphibians ( from frogs and toads), fish peptides, reptile peptides, birds, arthropods, insects, crustaceans, myriapods, chelicerata, spiders, scorpions, molluscs, AMPs from protozoa.
