DANMEL: A manually curated reference database for analyzing mobile genetic elements associated with bacterial drug...

Area of Science:

• Genomics
• Microbiology
• Bioinformatics

Background:

• Accurate genetic annotation of mobile genetic elements (MGEs) carrying drug resistance genes is crucial for understanding bacterial resistance mechanisms.
• Existing resources often lack detailed dissection and annotation of these MGEs.
• This gap hinders comprehensive genomic analysis of antimicrobial resistance.

Purpose of the Study:

• To develop and present DANMEL, a manually curated online database for reference MGEs with drug resistance genes.
• To provide a standardized guide for precise MGE annotation.
• To facilitate the identification and analysis of MGEs in bacterial genomes.

Main Methods:

• Manual curation of genetic structures of MGEs associated with drug resistance.
• Development of an online database (DANMEL) with search and BLAST functionalities.
• Inclusion of a detailed annotation guide within the database.

Main Results:

• DANMEL provides accurately annotated and genetically dissected reference MGEs.
• The database covers 5 major categories and 135 subcategories/subfamilies of MGEs.
• Integrated search and BLAST tools enable efficient retrieval of reference MGE data.

Conclusions:

• DANMEL addresses the need for precise MGE annotation and genetic dissection.
• The database serves as a valuable resource for researchers studying bacterial drug resistance.
• DANMEL facilitates in-depth genomic analysis of MGEs and enhances understanding of antimicrobial resistance at a genomic level.
