Retrieve brite hierarchy

brid = KEGG brite hierarchy identifer

DBGET Queries

Retrieve entries

db = Database name or KEGG organism name in full name or in abbreviation
entry = Entry name (accession number) or gene name

The second form is applicable to multiple entries in a single database.

(Examples)

(KEGG PATHWAY)	http://www.genome.jp/dbget-bin/www_bget?path:hsa05010
(KEGG GENES)	http://www.genome.jp/dbget-bin/www_bget?hsa:351 http://www.genome.jp/dbget-bin/www_bget?H.sapiens+APP+PSEN1
(KEGG LIGAND)	http://www.genome.jp/dbget-bin/www_bget?cpd:C00002 http://www.g.jp/dbget-bin/www_bget?rn:R05972
(Other databases)	http://www.genome.jp/dbget-bin/www_bget?sp:P05067 http://www.genome.jp/dbget-bin/www_bget?swissprot+A4_HUMAN

Retrieve sequence entries in FASTA format:

When the entry contains multiple sequences, specify as follows:
-f+-n+1 first sequence in FASTA format
-f+-n+2 second sequence in FASTA format
-f+-n+a amino acid sequence in FASTA format (KEGG GENES only)
-f+-n+n nucleotide sequence in FASTA format (KEGG GENES only)

(Examples)
http://www.genome.jp/dbget-bin/www_bget?-f+hsa:351
http://www.genome.jp/dbget-bin/www_bget?-f+-n+a+hsa:351
http://www.genome.jp/dbget-bin/www_bget?-f+-n+2+hsa:351

The list of options may be viewed by the -h option:

PATHWAY Queries

Mark pathway objects in red

mapid = pathway map identifier, such as map00010 and hsa00010
entry = gene identifier, compound identifier, ec number, etc.

(Examples)
http://www.genome.jp/kegg-bin/show_pathway?map00400+1.14.16.1+C00079+C00166
http://www.genome.jp/kegg-bin/show_pathway?hsa00400+5053+C00079+C00166

Mark pathway objects in any color

mapid = pathway map identifier, such as map00010 and hsa00010
keggid = KEGG identifer in the form of db:entry, where db: can be omitted
dcolor = default background color, "%3d" represents "=" in ASCII code
bgcolor = background color, "%09" represents TAB in ASCII code
fgcolor = foreground color

(Examples)
http://www.genome.jp/kegg-bin/show_pathway?map00400/ec:1.14.16.1/cpd:C00079/cpd:C00166
http://www.genome.jp/kegg-bin/show_pathway?map00400/default%3dpink/1.14.16.1%09,blue/C00079%09,red/cpd:C00166%09%23005050

(Note)
"%23" in color specification represents "#" in ASCII code.
The distinction of bgcolor/fgcolor is not really appropriate because it is applied to a GIF image file. Each object is identified from the coordinate file, thus, background coloring of a circular object applies to a square. Please consider using the XML representation of KEGG pathways for handling graphical objects.

SSDB Queries

Display conserved gene clusters

org:gene = KEGG GENES identifier (organism code and gene name)

(Example)
http://www.kegg.jp/ssdb-bin/ssdb_gclust?org_gene=syn:sll1450
