The Database of Antimicrobial Activity and Structure of Peptides (DBAASP) has been created to provide users with detailed information on experimentally tested peptides regarding their chemical structure and activity against specific targets. The database is manually curated and contains information on ribosomal, nonribosomal, and synthetic peptides that show antimicrobial activity as Monomers, Multimers, and Multi-Peptides.

Monomer – consists of one polypeptide chain (for example, Melittin, Magainin).

Multimer – consists of two or more polypeptide chains with an interchain covalent bond(s) (for example, Distinctin, Halocidin).

Multi-Peptide – consists of two or more distinct polypeptide chains without interchain covalent bonds. Their antimicrobial activity requires synergistic interaction between the peptides in equimolar concentrations as the individual peptides may have little or no activities (for example, Enterocin X, Salivaricin P).

Project was initially supported by Shota Rustaveli National Science Foundation (GEORGIA) and Centre National de la Recherche Scientifique (FRANCE).

Now it is a joint project between the Laboratory of Bioinformatics of Ivane Beritashvili Center of Experimental Biomedicine (IBCEB, GEORGIA) and  the Office of Cyber Infrastructure and Computational Biology (OCICB/NIAID/NIH, USA)
