This page summarises the third-party software, hosted assets, and scientific data sources used by AlphaSuite, together with their applicable licences, required copyright notices, and citation expectations. Where AlphaSuite displays, caches, or re-serves upstream material, the downstream terms of the originating provider apply.

3. Data Sources & Attribution

AlphaSuite relies on multiple public scientific resources. The summaries below describe what AlphaSuite uses each source for, the applicable licence, attribution requirements, and citation expectations. If you reuse AlphaSuite output in publications, reports, or downstream analysis, these attribution requirements apply to you.

UniProt

Used for: canonical protein accession resolution, sequence, entry names, protein names, organism labels, and summary metadata
Provider: UniProt (The UniProt Consortium)
Licence: Creative Commons Attribution 4.0 International (CC BY 4.0). Commercial use is permitted. Attribution is a legal requirement.
Terms: UniProt licence information
Required attribution: Credit “UniProt” and “The UniProt Consortium”
Preferred citation: The UniProt Consortium. UniProt: the Universal Protein Knowledgebase in 2023. Nucleic Acids Research, 51(D1), D523–D531 (2023). doi:10.1093/nar/gkac1052

InterPro

Used for: domain, family, site, repeat, and motif annotations, including linked functional descriptions. AlphaSuite surfaces annotations from InterPro member databases including Pfam, SMART, CDD, and PANTHER
Provider: InterPro at EMBL-EBI
Licence: EMBL-EBI open access terms — no additional restrictions on use. See EMBL-EBI Terms of Use
Required attribution: Credit “InterPro” and “EMBL-EBI”

PDBe

Used for: structure metadata, assembly information, structure-linked literature, PDBe Mol* viewer integration, and file or model delivery for some structure formats
Provider: PDBe at EMBL-EBI
Licence: EMBL-EBI open access terms. See EMBL-EBI Terms of Use
Required attribution: Credit “PDBe” and “EMBL-EBI”

SIFTS

Used for: residue-level mapping between UniProt sequence positions and experimental PDB coordinates, including chain-aware residue correspondence
Provider: SIFTS (PDBe / EMBL-EBI)
Licence: EMBL-EBI open access terms. See EMBL-EBI Terms of Use
Required attribution: Credit “SIFTS” and “EMBL-EBI”
Preferred citation: Velankar S. et al. SIFTS: structure integration with function, taxonomy and sequences resource. Nucleic Acids Research, 41(D1), D483–D489 (2013). doi:10.1093/nar/gks1258

RCSB PDB / wwPDB (Experimental Structures)

Used for: experimental coordinate files, PDB-format downloads, and accession-level structure availability
Provider: RCSB PDB on behalf of the wwPDB
Licence: CC0 1.0 Universal Public Domain Dedication. PDB archive structure data is placed in the public domain. No attribution is legally required, but crediting the wwPDB and original structure depositors is scientific good practice.
Terms: RCSB PDB policies
Preferred attribution: Credit the wwPDB / RCSB PDB and the relevant experimental structure accession(s)

AlphaFold DB (Predicted Structures)

Used for: predicted structure models for proteins where AlphaFold DB provides coverage
Provider: AlphaFold Protein Structure Database (DeepMind Technologies Limited / EMBL-EBI)
Licence: Creative Commons Attribution 4.0 International (CC BY 4.0). Commercial use is permitted. Attribution is a legal requirement. See the AlphaFold DB Licence & Disclaimer for full terms.

Preferred citation: Jumper J. et al. Highly accurate protein structure prediction with AlphaFold. Nature, 596, 583–589 (2021). doi:10.1038/s41586-021-03819-2

4. Delivery & Provenance Headers

AlphaSuite may cache and re-serve public structure files from upstream providers to support interactive viewing and downloads. Where AlphaSuite serves a structure or annotated structure file directly, HTTP response headers are included to identify the upstream provider and point back to their terms and to this attribution page. These headers include:

X-Structure-Provider — the name of the upstream data source
X-Structure-Provider-Url — the provider’s website
X-Structure-Terms-Url — the provider’s terms or licence page
X-AlphaSuite-Attribution-Url — this page

5. PyMOL Script Downloads

AlphaSuite can generate PyMOL annotation scripts (.pml files) for download. PyMOL is a molecular visualisation system developed by Schrödinger, LLC. PyMOL’s open-source version is available under a permissive licence; a commercial version is also available. AlphaSuite does not bundle or distribute any PyMOL software — it only generates plain-text scripts in the PyMOL scripting language. No licence from Schrödinger is required to generate or use .pml files. Generated scripts include data-source attribution comments referencing UniProt, InterPro, PDBe, SIFTS, and AlphaFold DB as applicable.
