Comparison of Gene Ontology Term Annotations between E.coli K12 Databases

The objective of this project was to get up-to-date functional information on all genes of E.coli K12 strains based on Genome Ontology terms. Gene Ontology is described by a defined library of terms related the biological process, cellular components and molecular functions of a gene in an organism. The genome sequence of an organism gains its value when it is annotated with gene ontology terms, which bridges the gap from the sequence to the biology of an organism. Since we use annotated gene database in the prediction of the function of newly sequenced genes, it is important to have databases that are complete and correctly annotated. In this study we compare multiple E. coli databases for consistency and completeness in their gene ontology terms
