| Entry | The KEGG PATHWAY database is a collection of manually drawn graphical diagrams (KEGG pathway maps) and associated text information (KEGG pathway entries) representing molecular pathways for metabolism, genetic information processing, environmental information processing, other cellular processes, human diseases, and drug development. Each pathway is identified by a five-digit number preceded by one of: map, ko, ec, rn, and three- or four-letter organism code. |
|---|---|
| Name | The name of the pathway followed by the organism name for the organism-specific pathway. |
| Description | A brief summary of the biological processes shown in the pathway map. |
| Class | The classification of the KEGG pathway maps, which is the basis for the KEGG Orthology (KO) system as can be seen by clicking on the 'BRITE hierarchy' link. |
| Pathway map | The corresonding KEGG pathway map. When viewing the reference pathway (ko) entries, the 'All organisms' and 'Ortholog table' links appear' These may help to understand the degree of gene conservation in complete genomes for each pathway node, as well as the completeness of the KEGG genome annotation. |
| Module | KEGG modules (complete modules only) that are part of this pathway. |
| Network | KEGG networks that are part of this pathway. |
| Disease | Links to KEGG DISEASE when genes in this pathway are known to be associated with diseases. |
| Drug | Links to KEGG DRUG when gene products in this pathway are known drug targets. |
| Other DBs | Links to outside databases. |
| Organism | The organism name for organism-specific pathways. |
|
Orthology Gene Enzyme Reaction | The list of pathway nodes for genes and proteins (boxes in the pathway maps). They are KO groups, enzymes, or reactions for the reference pathways, and genes for organism-specific pathways. |
| Compound | The list of pathway nodes for chemical substances (circles in the pathway maps). |
| Reference | Original references used for manually drawing the pathway map. This field appears only in the KO pathway entry or the DRUG map entry. |
| Related pathway | The list of pathways that are linked from this entry. |
| KO pathway | Link to the corresponding KO pathway entry. |
| LinkDB | 'All DBs' button in this field retrieves all available links to related database entries in the LinkDB system. At GenomeNet this field does not appear; instead a list of actual links is displayed on the right. |
