ELM Downloads

Below you'll find examples of the different ways that can be used to query ELM programmatically. No special client is needed for this just a browser or maybe "curl"/"wget" for scripted access. By using these access methods you implicitly agree to using/distributing this data according to the ELM Software License Agreement.

ClassesLast modified on: May 13, 2024, 4:35 p.m.

Here you can download a list of ELM classes, either all at once or limit the list by providing a query term "q".

Name Example URL
all html /elms/elm_index.html
all tsv /elms/elms_index.tsv
by query term tsv /elms/elms_index.tsv?q=PCSK
by ELM id html /ELME000012.html

InstancesLast modified on: Jan. 30, 2024, 4:28 p.m.

Annotated ELM instances can be queried in a variety of ways. You are encouraged to use the search form to get a feeling for the parameters. Common examples include limiting the query by either instance logic or taxon.

Name Example URL
all html /elms/instances.html?q=*
by Uniprot acc fasta instances.fasta?q=P12931
by Uniprot name gff instances.gff?q=SRC_HUMAN
by Uniprot acc tsv instances.tsv?q=P12931
by query term pir instances.pir?q=PCSK
by query term tsv instances.tsv?q=src
by query term mitab instances.mitab?q=src
by query term xml instances.psimi?q=src
by query term using additional parameter "instance logic" tsv instances.tsv?q=src&instance_logic=true+positive
by Instance id html /ELMI000123.html
All docking motifs annotated in taxon "mouse" tsv instances.tsv?q=DOC_&taxon=mus+musculus

InteractionsLast modified on: Jan. 30, 2024, 4:28 p.m.

Interactions between annotated ELM instances and the corresponding globular interaction partner can be queried as follows. Data is provided either in simple TSV (tab-separated values), PsiMi XML or in MiTAB format.

Name Example URL
all interactions tsv /interactions/as_tsv
all interactions mitab /interactions/as_mitab
all interactions psimi /interactions/as_psimi
all interactions from certain taxon mitab /interactions/as_mitab?taxon=mus%20musculus
by Interaction id mitab /interactions/ELMINT000120.mitab
by Interaction id xml /interactions/ELMINT000120.xml
by Uniprot acc mitab /interactions/P33379.mitab
by Uniprot acc xml /interactions/P02751.xml

Interaction DomainsLast modified on: Oct. 21, 2023, 1:03 p.m.

List of all domains annotated as interacting with one or more ELM class.

Name Example URL
all interaction domains html /infos/browse_elm_interactiondomains.html
all interaction domains tsv /infos/browse_elm_interactiondomains.tsv

MethodsLast modified on: Sept. 25, 2023, 3:19 p.m.

The following table holds all methods which have been used during the ELM rigourous data curation process.

Name Example URL
all methods html /infos/browse_elm_methods.html
all methods tsv /infos/browse_elm_methods.tsv

PDBsLast modified on: Jan. 30, 2024, 4:27 p.m.

The following table holds all PDBs which are annotated in the ELM database.

Name Example URL
all PDBs html /pdbs/
all PDBs tsv /pdbs.tsv

GOTermsLast modified on: Oct. 20, 2023, 5:36 p.m.

The following table shows the GOTerms which are annotated per ELM class.

Name Example URL
all GOTerms html /goterms
all GOTerms tsv /goterms.tsv

PathwaysLast modified on: Oct. 20, 2023, 5:36 p.m.

The following tables shows the Pathways which are annotated per ELM instance.

Name Example URL
all KEGG terms html /kegg_terms.html
all KEGG terms tsv /kegg_terms.tsv
all Reactome terms html /reactome_terms.html
all Reactome terms tsv /reactome_terms.tsv

Renamed ELM classesLast modified on: June 20, 2016, 4:45 p.m.

The following table holds all ELM classes that have been renamed in the past.

Name Example URL
all renamed ELM classes tsv /infos/browse_renamed.tsv
