The eggNOG database is a database of biological information hosted by the EMBL . It is based on the original idea of COGs (clusters of orthologous groups)[ 2] [ 3] and expands that idea to non-supervised orthologous groups constructed from numerous organisms.[ 4] The database was created in 2007[ 5] and updated to version 4.5 in 2015.[ 1] eggNOG stands for e volutionary g enealogy of g enes: N on-supervised O rthologous G roups .
