BRENDA

Unique in quality, depth and coverage of the relevant contents.

BRENDA is the most comprehensive information repository on enzymes and enzyme ligand data. The BRENDA enzyme information system has developed into an elaborate system of enzyme and enzyme-ligand information obtained from different sources, combined with flexible query systems and evaluation tools. BRENDA has been developed and is maintained by the Institute of Biochemistry and Bioinformatics at the Technical University of Braunschweig, Germany. Data on enzyme function are extracted manually from primary literature, and are complemented by text and data mining, data integration, and prediction algorithms.
The curation process has been designed to ensure a maximum of quality, depth and coverage of the contents of this unique database. Formal and consistency checks are done by an elaborate computational pipeline. All enzymes in BRENDA are classified according to the biochemical reaction catalyzed, and are assigned to the corresponding Enzyme Commission (EC) numbers. Reaction kinetics are described in detail. BRENDA’s intuitive user interface support a wide range of queries such as fast full text search, advanced complex queries or searching via sequence or substructure. Browsing the contents is facilitated by a Taxonomic Tree, an Enzyme class, a Genome or an Ontology explorer.

Structure

The data sources of BRENDA comprise three main domains: Text mining data, manual annotation and external databases and ontologies.
Organization of BRENDA® contents
The supplementary sources FRENDA (enzyme name & organism), AMENDA (enzyme name & organism & occurence), DRENDA (disease-related enzyme data) and KENDA (kinetic data) complement the BRENDA core by text mining data.
The manually annotated core is based on IUBMB enzyme classes and literature from PubMed. Additionally, the BRENDA tissue ontology (BTO) is linked to the manual annotation.
Cross references to several external databases like UniProt, PDB, MetaCyc, ChEBI, KEGG, EMBL, and the Taxonomy Browser of NCBI further expand BRENDA.

Key features

Enzyme and enzyme-ligand information is obtained from different sources, combined with flexible query systems and evaluation tools.
The data are acquired by manual extraction from primary literature, text and data mining, data integration, and prediction algorithms.
The manually derived core contains >3 million data points about 77,000 enzymes annotated from 135,000 literature references.
BRENDA comprises molecular data from more than 30,000 organisms.
Each entry is linked to its publication source and the organism of origin. The entries are supplemented by information on occurrence, enzyme / disease relationships from text mining, sequences and 3D structures from other databases, and predicted enzyme location and genome annotation.
The human anatomy atlas CAVEman is linked to the BRENDA Tissue Ontology terms connecting functional enzyme data with their anatomical location.
Word Maps for enzymes generated from PubMed abstracts highlight application and scientific relevance of enzymes.
The EnzymeDetector genome annotation tool and the reaction database BKM-react including reactions from BRENDA, KEGG and MetaCyc.
BRENDA is the most comprehensive information repository on enzymes with 7,095 EC numbers (December 2016)
