alphafold-db

separate

Access over 200M protein structures from AlphaFold DB; use when you need to retrieve predicted 3D structures (PDB/mmCIF), confidence metrics (pLDDT/PAE), or protein metadata by UniProt accession.

When to use

• You have a UniProt accession (e.g., `P00520`) and need to download its AlphaFold-predicted 3D structure in **mmCIF** or **PDB** format.
• You want to assess prediction reliability using **per-residue pLDDT** confidence scores.
• You need **PAE (Predicted Aligned Error)** data to support domain-level interpretation or inter-domain confidence checks.
• You want to programmatically retrieve AlphaFold DB **metadata** (e.g., model/structure URLs and related fields) for downstream pipelines.
• You are building an automated workflow that fetches structures + confidence metrics for many proteins by UniProt ID.
