The SWISS-MODEL Repository is a database of annotated 3D protein structure models generated by the SWISS-MODEL homology-modelling pipeline.

Bienert S, Waterhouse A, de Beer TA, Tauriello G, Studer G, Bordoli L, Schwede T (2017). The SWISS-MODEL Repository - new features and functionality Nucleic Acids Res. 45(D1):D313-D319.

The aim of the SWISS-MODEL Repository is to provide access to an up-to-date collection of annotated 3D protein models generated by automated homology modelling for relevant model organisms and experimental structure information for all sequences in UniProtKB. Regular updates ensure that target coverage is complete, that models are built using the most recent sequence and template structure databases, and that improvements in the underlying modelling pipeline are fully utilised. It also allows users to assess the quality of the models using the latest QMEAN results. If a sequence has not been modelled, the user can build models interactively via the SWISS-MODEL workspace.

Currently the repository contains 1,079,191 models from SWISS-MODEL for UniProtKB targets as well as 129,418 structures from PDB with mapping to UniProtKB.

We currently provide models for the reference proteomes of the following model organisms, based on UniProtKB release 2017_12. If you want to download a large number of models, please contact us.

Note that from January 2018, the SMR API has been extended to provide a real JSON object, with more useful information about the structures, as well as the UniProtKB sequence matching the query. Please see the documentation for more help.
