DRAMP: a comprehensive data repository of antimicrobial peptides

Area of Science:

• Biochemistry
• Molecular Biology
• Drug Discovery

Background:

• The rise of antibiotic-resistant microorganisms demands novel therapeutic strategies.
• Antimicrobial peptides (AMPs) are natural defense molecules with broad-spectrum activity and low resistance potential, making them promising antibiotic alternatives.
• Comprehensive understanding and accessibility of AMP data are crucial for their development into clinical drugs.

Purpose of the Study:

• To develop a user-friendly, comprehensive data repository for antimicrobial peptides (AMPs).
• To facilitate research and development of novel antimicrobial peptide-based drugs.

Main Methods:

• Compilation of 17,349 antimicrobial peptide sequences from various sources, including general AMPs, patented sequences, and those in drug development.
• Detailed annotation of each entry with antimicrobial activity (MIC values against target organisms), structural information, and cross-references to PubMed, Swiss-Prot, and PDB.
• Development of a website with advanced browsing, searching, sorting, filtering, and sequence analysis tools (similarity search, alignment, CD-Search).

Main Results:

• The DRAMP database contains 17,349 antimicrobial sequences, including 4,571 general AMPs, 12,704 patented sequences, and 74 peptides in drug development.
• Entries feature detailed annotations on antimicrobial activity and structure, with cross-links to major biological databases.
• The platform offers robust data management and analysis functionalities for users.

Conclusions:

• DRAMP provides a valuable, comprehensive resource for researchers and drug developers in the field of antimicrobial peptides.
• The database and its associated tools are expected to accelerate the discovery and development of novel antimicrobial peptide drugs to combat microbial resistance.
