FRENDA (Full Reference ENzyme DAta) is a supplement to BRENDA that is available to the public since BRENDA release 6.2 (June 2006). FRENDA aims at providing an exhaustive collection of literature references containing organism-specific enzyme information.
Contents of FRENDA(January 2010)
FRENDA currently covers nearly 6 million enzyme/organism/reference combinations (nearly 400,000 enzyme/organism combinations) extracted from about 20 million PubMed abstracts.
More than 20 million PubMed reference - titles and when available abstracts - (status: June 2010) are analyzed in a cooccurence based textmining approach. FRENDA uses a dictionary-based approach for detecting named entities in titles
and abstracts. Search terms for enzyme names and organism names are compiled from BRENDA and
The text mining results were classified into 4 reliability categories depending on the
occurrence of search terms in title and/or abstract and/or MeSH terms. This classification
is provided with the commentaries in the FRENDA database.
