the Clusters of Orthologous Groups of proteins COGs

Online

Alternative name: COG database | the Clusters of Orthologous Groups of proteins COGs

Provides clusters of orthologous groups (COGs) and updated annotation of those COGs. COGs is a database where organisms are sorted according to the NCBI Taxonomy database. Each gene entry in a COG is now denoted by its gene index (gi) number in the NCBI protein database and is linked to the respective entry in the NCBI’s RefSeq database. It concentrates on prokaryotes (bacteria and archaea).
