What is a cog category?
What is a cog category?
The Clusters of Orthologous Groups (COGs) of proteins were generated by comparing the protein sequences of complete genomes. Each cluster contains proteins or groups of paralogs from at least three lineages. The current COG database contains both prokaryotic clusters (COGs) and eukaryotic clusters (KOGs).
What is COG genes?
COGs stands for Clusters of Orthologous Genes. The database was initially created in 1997 (Tatusov et al., PMID: 9381173) followed by several updates, most recently in 2014 (Galperin et al., PMID: 25428365). The current update includes complete genomes of 1,187 bacteria and 122 archaea that map into 1,234 genera.
What is a cog in microbiology?
A collection of homologous genes that are useful for study of evolutionary relationships.
What are COGs in bioinformatics?
The database of Clusters of Orthologous Groups of proteins (COGs) is an attempt on a phylogenetic classification of the proteins encoded in 21 complete genomes of bacteria, archaea and eukaryotes (http://www.ncbi.nlm.nih.gov/COG ).
What is COG name?
The surname Cog was first found in Northampton where they held a family seat as Lords of the Manor. The Saxon influence of English history diminished after the Battle of Hastings in 1066. But Saxon surnames survived and the family name was first referenced in the 12th century when Robert Cog held estates in that shire.
What is the full form of COG?
COG – Cost of Goods.
What are human orthologs?
Orthologs are genes which evolved from a common ancestral gene by speciation that usually have retained a similar function in different species. Paralogs are genes related by duplication within the genome and often they acquire a new function.
How many CPGS are in the human genome?
The human genome contains ∼30,000 CpG islands (CGIs), long stretches (0.5–2 kb) of DNA with unusually elevated levels of CpG dinucleotides. Many occur at genes’ promoters, and their DNA nearly always remains unmethylated.
What is eggNOG Mapper?
eggNOG-mapper is a tool for functional annotation of large sets of sequences based on fast orthology assignments using precomputed clusters and phylogenies from the eggNOG database. Orthology assignment is ideally suited for functional inference.
What’s the difference between a cog and a gear?
A “cog” is an individual tooth on a cogwheel. The terms can be interchangeable, but cog usually refers to a simple spur gear. A gear can be a spur, bevel, helical, worm, hypoid etc. A gear or cogwheel is a rotating machine part having cut teeth, or cogs, which mesh with another toothed part to transmit torque.
What does cog stand for in construction?
Cost of goods sold (COGS) makes up a substantial portion of construction contractors’ expenses. Most purchases are related to projects, either for labor or materials. Tracking these costs and keeping them separate from regular business expenses is key when it comes to measuring job profitability.
What are the functional categories associated with each cog?
While each COG has a specific functional description, it may also have one or more general category letter associations: [D] Cell cycle control, cell division, chromosome partitioning [O] Post-translational modification, protein turnover, and chaperones
What are the cog and Kogs classified into?
The COGs and KOGs are classified into functional classifications. The functional categories are not listed on the new version of the COG website. They are designated in the papers and listed below for convience. It should be noted that the updated version of the COG database does not have functional interactions with COGs.
What does cogs stand for?
The Clusters of Orthologous Groups (COGs) of proteins were generated by comparing the protein sequences of complete genomes. Each cluster contains proteins or groups of paralogs from at least three lineages. The current COG database contains both prokaryotic clusters (COGs) and eukaryotic clusters (KOGs). Although the COGS categorization of
How many proteins are in the cog?
The COG database collection consists of 138,458 proteins from 66 genomes. These proteins form 4873 COGs. As noted above, these COGs, though listed in the new version, has no website function.
