摘要
En 中文
The Clusters of Orthologous Genes (COG) database, originally created in 1997, has been updated to reflect the constantly growing collection of completely sequenced prokaryotic genomes. This update increased the genome coverage from 1309 to 2296 species, including 2103 bacteria and 193 archaea, in most cases, with a single representative genome per genus. This set covers all genera of bacteria and archaea that included organisms with 'complete genomes' as per NCBI databases in November 2023. The number of COGs has been expanded from 4877 to 4981, primarily by including protein families involved in bacterial protein secretion. Accordingly, COG pathways and functional groups now include secretion systems of types II through X, as well as Flp/Tad and type IV pili. These groupings allow straightforward identification and examination of the prokaryotic lineages that encompass-or lack-a particular secretion system. Other developments include improved annotations for the rRNA and tRNA modification proteins, multi-domain signal transduction proteins, and some previously uncharacterized protein families. The new version of COGs is available at https://www.ncbi.nlm.nih.gov/research/COG, as well as on the NCBI FTP site https://ftp.ncbi.nlm.nih.gov/pub/COG/, which also provides archived data from previous COG releases.
