KEGG Atlas may now be used to examine any of the KEGG pathway maps.
Pathway Entries and Pathway Modules
Pathway entries are text representation of pathway maps, containing descriptions (for a limited number of entries, at the moment). Pathway modules are specification of subnetworks that correspond to tighter functional units, each represented as a list of KO identifiers (K numbers).
KEGG PATHWAY mapping is the process to map molecular datasets, especially large-scale datasets in genomics, transcriptomics, proteomics, and metabolomics, to the KEGG pathway maps for biological interpretaion of higher-level systemic functions.
