===AlphaFold3 Chain IDs=== | ===AlphaFold3 Chain IDs=== | ||
The [https://alphafoldserver.com AlphaFold Server], which in 2025 uses AlphaFold3<ref name="af3">PMID: 38718835</ref>, predicts complexes with multiple chains of protein and/or nucleic acid, plus a limited set of ligands, and metal ions, and a wide range of post-translational modifications of amino acids and chemical modifications of nucleotides. Predicted models are available in mmCIF format only (not PDB format, although the mmCIF files can be [[Converting AlphaFold3 CIF to PDB|easily converted to PDB format]]). Consistent with the chain ID assignment policies of the wwPDB for mmCIF files, every entity is assigned a unique chain ID, including polymer chains, ligands, metal ions, and glycans including oligo- and monosaccharides. | The [https://alphafoldserver.com AlphaFold Server], which in 2025 uses AlphaFold3<ref name="af3">PMID: 38718835</ref>, predicts complexes with multiple chains of protein and/or nucleic acid, plus a limited set of ligands, and metal ions, and a wide range of post-translational modifications of amino acids and chemical modifications of nucleotides.
