 * data retrieve 
 * sequence search and analysis
 * derived DBs
 * other DBs

= PDBj =

= KEGG =

= first concentrate on sequence + alignment =

= functional annotations =
a given structure with unknown function -> BLAST at DDBJ / KEGG -> no homologs then -> struct-navi 

 * accession number -> fasta 

 * PDB ID <-> KEGG GENES ID ''get_linkdb_between_databases(string:from_db, string:to_db, int:offset, int:limit)''
