Colibri: a functional data base for the Escherichia coli genome

Area of Science:

• Genomics
• Bioinformatics
• Molecular Biology

Background:

• Existing Escherichia coli genome data is extensive, exceeding 40% of the whole sequence.
• There is a need to organize this data to link experimental knowledge to specific genes and their genomic context.
• Global gene properties require appropriate description fields as new data emerges.

Purpose of the Study:

• To describe a novel database for organizing Escherichia coli genome data.
• To facilitate the association of experimental knowledge with gene positions and relationships.
• To present biologically significant results derived from data analysis.

Main Methods:

• Implementation of a database on Macintosh using the 4th Dimension system.
• Construction around known E. coli sequence contigs.
• Linking general libraries with evolving knowledge through modifiable fields.
• Application of learning or statistical data analysis procedures.

Main Results:

• A structured database integrating genomic sequence and experimental data for E. coli.
• Identification of biologically significant findings through data analysis.
• The database is accessible via 4th Dimension runtime and FTP.

Conclusions:

• The developed database effectively organizes complex E. coli genome information.
• This approach enhances the ability to associate gene knowledge with genomic context.
• Future integration with other E. coli databases is planned.
