Schematic representation of the utilities available for databases available at the KEGG resource. Arrows connecting the databases indicate directionality of searching the databases using BDE utilities. Unidirectional arrows indicate search of target database (to which arrow-head is pointed) using keywords/data types from the resource database. Bidirectional arrows indicate utilities that facilitate two-way searches of databases
