Predicted function of the proteins identified by proteomics is based on comparisons of the genes in the metagenome to the pfam, Clusters of Orthologous Groups (COGs), and the Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. The IMG gene oid is the gene identifier for The Joint Genome Institute's Integrated Microbial Genomes database http://img.jgi.doe.gov/. The pfam assignment of the metagenome gene is indicated.
