DrugBank MITAB2.6 File Format

From irefindex

Last edited: 2011-08-25


This document describes usage of the PSI-MITAB2.6 format in order to represent the drug-protein and drug-drug interactions provided by DrugBank in a form suitable for consumption by MITAB-aware tools and services such as MITAB parsers and PSICQUIC Web services.

Although MITAB2.6 is used by iRefIndex (as described in the format documentation), certain elements of that extended format are not directly applicable to DrugBank data, whereas other elements (such as a general checksum for an interactor) are applicable but not directly equivalent to the kind of data provided by iRefIndex: although a drug may have an InChIKey - a form of checksum or hash of the chemical structure of the drug - it is not equivalent or directly comparable to the ROG (redundant object group) employed by iRefIndex.

Format Summary

Note that each record describes a drug-drug or drug-protein interaction where the second interactor (uidB) may be either a protein or a small molecule. Where uidB is a protein, it will always have a UniProt accession as an identifier: interactors not having a UniProt reference are excluded from the MITAB output.

Field Description Example Source
uidA A DrugBank identifier drugbank:DB00123 drug/drugbank-id
uidB For proteins: the given UniProt identifiers
For drugs: see uidA
UniProtKB:P18440 <partner>/external-identifiers/external-identifier/identifier (for proteins)
altA DrugBank secondary accessions having the form drugbank:accession (compatible with MI:2002)
InChIKey values of the form inchikey:key
External identifiers for the drug
altB For proteins: external identifiers (other than UniProt identifiers) of the form database:identifier
For drugs: see altA
GNC:7645 <partner>/external-identifiers/external-identifier/identifier (for proteins)
aliasA DrugBank synonyms and brand names using drugbank_synonym and drugbank_brand as qualifiers drugbank_synonym:Hirudin variant-1
aliasB For proteins: synonyms having the form drugbank_synonym:protein name
For drugs: see aliasA
drugbank_synonym:Arylamine N-acetyltransferase 1 <partner>/name (for proteins)
