Functional Hierarchies

[ New BRITE files | Update history ]
KEGG BRITE is a collection of manually created hierarchical text (htext) files capturing functional hierarchies of various biological objects, especially those represented as KEGG objects. Some BRITE hierarchy files contain tab-delimited attributes that are added manually or computationally. BRITE table files are now used to focus more on such multi-column attributes rather than hierarchy relationships. In contrast to KEGG PATHWAY, which is limited to molecular interactions and reactions, KEGG BRITE incorporates many different types of relationships including: KEGG BRITE is a reference database for Brite Mapping.

Brite Identifiers

Each brite hierarchy/table is identified by the combination of 2-4 letter prefix code and 5 digit number (see KEGG Identifier). The prefix has the following meaning:
br
non-gene/protein reference hierarchy or table
jp
non-gene/protein reference hierarchy or table in Japanese
ko
gene/protein reference hiearchy for KO expansion
<org>
organism-specific hierarchy generated by converting KOs to gene identifiers

Brite Mapping

KEGG BRITE mapping is the process to map molecular datasets, especially large-scale datasets in genomics, transcriptomics, proteomics, and metabolomics, to the BRITE functional hierarchies for biological interpretation of higher-level systemic functions.
