EggNOG (Evolutionary Genealogy of Genes: Non-supervised Orthologous Groups) database collects 5,090 organisms (477 eukaryotes, 4,445 representative bacteria and 168 archaea) and 2,502 viruses COG (Clusters of Orthologous Groups of proteins). Each COG is assumed to be from an ancestor, and each protein has an integrated and summarized functional annotation. EggNOG can provide COG at different classification levels, divide these species into 379 taxonomic levels, and the number of each category is represented by the NCBI classification number. EggNOG classified homologous genes for the COG of each species, and carries out multiple sequence alignment, phylogenetic tree construction, HMM file construction and functional annotation for each homologous gene category.
The EggNOG database is an extension of NCBI's COG database, and EggNOG collects more comprehensive species and a larger amount of protein sequence data. The cluster analysis of homologous genes and the description and function classification of each homologous gene class are also carried out.
