MimoDB 2.0: a mimotope database and beyond

Area of Science:

• Biochemistry
• Bioinformatics
• Immunology

Background:

• Mimotopes are peptides with specific target affinities, crucial for understanding protein interactions and developing diagnostics, therapeutics, and vaccines.
• Existing central databases like UniProt and NCBI GenPept do not curate mimotopes due to their short, 'unnatural' sequences.
• MimoDB serves as a dedicated information portal for biopanning results from random peptide libraries.

Purpose of the Study:

• To present MimoDB version 2.0, a comprehensive database of mimotopes.
• To provide a valuable resource for researchers in diagnostics, therapeutics, and vaccine development.
• To offer tools and benchmarks for bioinformaticians and experimental biologists.

Main Methods:

• Collected 15,633 mimotopes from 849 scientific papers.
• Organized peptides into 1818 distinct sets.
• Integrated data on panning experiments, targets, templates, libraries, and structures.

Main Results:

• MimoDB 2.0 contains 15,633 peptides from 849 publications, grouped into 1818 sets.
• The database includes extensive background information on targets, templates, libraries, and structures.
• A benchmark dataset is provided for developing and evaluating bioinformatics tools.

Conclusions:

• MimoDB 2.0 is a vital resource for mimotope data, supporting research in diagnostics, therapeutics, and vaccines.
• The database offers practical tools for experimental biologists, including virtual controls for target-unrelated peptide identification.
• MimoDB enhances the accessibility and utility of mimotope information for the scientific community.
