Pathway Maps

[ New pathway maps | Update history ]
KEGG PATHWAY is a collection of manually drawn pathway maps representing our knowledge of the molecular interaction, reaction and relation networks for: KEGG PATHWAY is the reference database for pathway mapping in KEGG Mapper.

Pathway Identifiers

Each pathway map is identified by the combination of 2-4 letter prefix code and 5 digit number (see KEGG Identifier). The prefix has the following meaning:
manually drawn reference pathway
reference pathway highlighting KOs
reference metabolic pathway highlighting EC numbers
reference metabolic pathway highlighting reactions
organism-specific pathway generated by converting KOs to gene identifiers
and the numbers starting with the following:
global map (lines linked to KOs)
overview map (lines linked to KOs)
chemical structure map (no KO expansion)
drug structure map (no KO expansion)
regular map (boxes linked to KOs)
are used for different types of maps.

KEGG PATHWAY is integrated with MODULE and NETWORK databases as indicated below.
M - module
R - reaction module
N - network
