A mutation spectra database for bacterial and mammalian genes

Area of Science:

• Genetics
• Molecular Biology
• Bioinformatics

Background:

• Understanding mutation spectra is crucial for deciphering DNA damage and repair mechanisms.
• Existing data on mutation spectra were fragmented, hindering comprehensive analysis.

Purpose of the Study:

• To create a centralized, accessible database of mutation spectra.
• To facilitate the analysis of mutation patterns across different genes and organisms.

Main Methods:

• Compilation of mutation data from induced and spontaneous mutations in bacterial, phage, mammalian, and yeast genes.
• Development of a web-accessible database with downloadable data tables.
• Implementation of a data entry program (MUTSIN) for quality control.

Main Results:

• The database contains 240 datasets with 24,500 mutants across nine bacterial, two phage, five mammalian, and one yeast gene.
• Data is available in text and dBASE III formats for versatile use.
• The database is accessible online at http://info.med.yale.edu/mutbase/.

Conclusions:

• The mutation spectrum database provides a valuable resource for genetic and molecular biology research.
• The database supports large-scale analyses of mutation patterns and aids in understanding mutagenic processes.
• Researchers are encouraged to contribute data to expand the database's scope.
