Color tool

The Color tool searches various KEGG objects, including genes, KOs, EC numbers, metabolites and drugs, against KEGG pathway maps. Found objects may be marked in any combination of background and foreground colors.
See new article: KEGG mapping tools for uncovering hidden features in biological data

Search mode:   Reference   hsa   other org

Enter KEGG identifiers followed by color specification

(Notice) Use of gene symbols
The use of gene symbols (in the Gene name field of GENES entry) as aliases is no longer supported, because many-to-many relationships may result in erroneous links to KEGG identifiers.

As an exception, the official symbols for hsa (Homo sapiens) can be used as primary identifiers, which are automatically converted to KEGG identifiers by using the one-to-one correspondence between NCBI Gene IDs and HGNC symbols. Note, however, that the correspondence is updated every three months of RefSeq releases. It is highly recommended to always use KEGG hsa gene identifiers.
