COG Clusters of Orthologous Groups
Clusters of Orthologous Groups (COG) is a phylogenetic classification of proteins encoded in complete genomes.
- Information storage and processing
- Cellular processes and signaling
- D, Cell cycle control, cell division, chromosome partitioning
- M, Cell wall/membrane/envelope biogenesis
- N, Cell motility
- O, Posttranslational modification, protein turnover, chaperones
- T, Signal transduction mechanisms
- U, Intracellular trafficking, secretion, and vesicular transport
- V, Defense mechanisms
- W, Extracellular structures
- Y, Nuclear structure
- Z, Cytoskeleton
- Metabolism
- C, Energy production and conversion
- E, Amino acid transport and metabolism
- F, Nucleotide transport and metabolism
- G, Carbohydrate transport and metabolism
- H, Coenzyme transport and metabolism
- I, Lipid transport and metabolism
- P, Inorganic ion transport and metabolism
- Q, Secondary metabolites biosynthesis, transport and catabolism
- Poorly characterized
