Search tool
The Search tool searches various KEGG objects, including genes, KOs, EC numbers, metabolites and drugs, against KEGG pathway maps and other network entities. Found objects are marked in red.
Usage
Query data format
KEGG identifiers separated by whitespace characters (space, tab, newline)

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.
