The NCBI COG page shows protein families (COGs) that are encoded (or not) in the
genomes of E. coli strains K12 and O157. Clicking on any link brings a
window that allows to search the whole COG database by E.coli gene name.
The link provided here opens the COG page for all enterobacteriacea. If you want to
to a species specific site, e.g. E.coli K12 or E.coli O157 please use the NCBI genomes page, which is also linked to on this portal. The genomes page provides a specific
COG link, which starts one level higher. A direct species specific link is not provided.
