Clusters of Orthologous Groups (COGs) are sets of orthologous protein-coding sequences that can be used to rapidly assign functional annotations to whole genome sequences. In this article, we provide a table that contains the COG initial, its color code, and its function name.

COG Initial Hex Color Code Function Name
J #ff0000 Translation, ribosomal structure and biogenesis
A #c2af58 RNA processing and modification
K #ff9900 Transcription
L #ffff00 Replication, recombination and repair
B #ffc600 Chromatin structure and dynamics
D #99ff00 Cell cycle control, cell division, chromosome partitioning
Y #493126 Nuclear structure
V #ff008a Defense mechanisms
T #0000ff Signal transduction mechanisms
M #9ec928 Cell wall/membrane/envelope biogenesis
N #006633 Cell motility
Z #660099 Cytoskeleton
W #336699 Extracellular structures
U #33cc99 Intracellular trafficking, secretion, and vesicular transport
O #00ffff Posttranslational modification, protein turnover, chaperones
C #9900ff Energy production and conversion
G #805642 Carbohydrate transport and metabolism
E #ff00ff Amino acid transport and metabolism
F #99334d Nucleotide transport and metabolism
H #727dcc Coenzyme transport and metabolism
I #5c5a1b Lipid transport and metabolism
P #0099ff Inorganic ion transport and metabolism
Q #ffcc99 Secondary metabolites biosynthesis, transport and catabolism
R #ff9999 General function prediction only
