EggNOG is a database of biological information hosted by the EMBL. It is based on the original idea of COGs (clusters of orthologous groups) and expands that idea to non-supervised orthologous groups constructed from numerous organisms. eggNOG stands for evolutionary genealogy of genes: Non-supervised Orthologous Groups.
This class extends
list and contains:
cogFunctionalCategories": Cluster of Orthologous Groups
(COG) functional category information.
annotations": up-to-date functional descriptions and categories
for Eukaryotes Non-supervised Orthologous Groups (euNOG)
and Non-supervised Orthologous Groups (NOG) protein
The EggNOG README contains additional useful reference information.
