Dataset description:

The Encyclopedia of Domains (TED) is a joint effort by CATH (Orengo group) and the Jones group at University College London to identify and classify protein domains in AlphaFold2 models from AlphaFold Database version 4, covering over 188 million unique sequences and 324 million domain assignments.

In this data release, we will be making available to the community a table of domain boundaries and additional metadata on quality (pLDDT, globularity, number of secondary structures), taxonomy and putative CATH SuperFamily or Fold assignments for all 324 million domains in TED100.

For all chains in the TED-redundant dataset, the attached file contains boundaries predictions, consensus level and information on the TED100 representative.

Additionally, an archive with chain-level consensus domain assignments are available for 21 model organisms and 25 global health proteomes:

For both TED100 and TEDredundant we provide domain boundaries predictions outputted by each of the three methods employed in the project (Chainsaw, Merizo, UniDoc).

We are making available 7,427 novel folds PDB files, identified during the TED classification process with an annotation table sorted by novelty.

Please use the gunzip command to extract files with a '.gz' extension.

CATH annotations have been assigned using the FoldSeek algorithm applied in various modes and the FoldClass algorithm, both of which are used to report significant structural similarity to a known CATH domain.
Note: The TED protocol differs from that of our standard CATH Assignment protocol for superfamily assignment, which also involves HMM-based protocols and manual curation for remote matches.

Here are deposited all of the predictions generated for the test cases presented in "AlphaFold Unmasked: integration of experiments and predictions with a smarter template mechanism" (doi: https://doi.org/10.1101/2023.09.20.558579) along with the log files necessary to reproduce the experiments.

Each tar.gz file includes one or more AlphaFold experiments, where multiple predictions have been generated either with AlphaFold-Multimer (standard pipeline, v2.2 and/or v2.3 parameters) or with AF_unmasked. An experiment is made of a set of 3D structure predictions (.pdb files) along with the ancillary data generated by AlphaFold (pickle files) and the corresponding inputs (Multiple Sequence Alignments, sequences). Scripts to reproduce the results are included along with the log files generated during the experiments.

H1111, H1142, T1109 and T1110 are multimeric prediction targets from CASP15 (https://predictioncenter.org/casp15/) chosen because most or all predictors failed to correctly predict these complexes in the 2021 edition of CASP.

Rubisco, NF1 and ClpB are examples of large and/or challenging targets where Cryo-EM data is available to be integrated in the prediction pipeline.

The PDB benchmark is made of a set of protein heterodimeric structures deposited in the PDB before January 2022, i.e. before AlphaFold v2.3 was trained and released. These heterodimers have been redundancy reduced by structural similarity (MMalign score threshold: 0.4) to increase their diversity

In this work, we are using AlphaFold structure models to find the closest homologues proteins between Homo sapiens and D. melanogaster, C. elegans, S. cerevisiae and S. pombe as well as between S. cerevisiae and S. pombe. We are using the structure aligner Foldseek to run all against all and search for the best scoring hit in both directions to detect the Reciprocal Best Structure Hits (RBSH). We compare the results to protein pairs detected by their sequence similarity as Reciprocal Best Hits (RBH) and verify the results using the PANTHER family classification files. \( \ \) Note: This dataset is an updated version of the dataset at https://doi.org/10.17863/CAM.85487.

Description: TMvis ("TMvis496.tar.gz") is a dataset containing 496 3D-structures of predicted human transmembrane proteins (TMP) and their predicted membrane embedding. The method TMbed [1], based on the protein language model ProtT5 [2] predicted 4.967 TMP for the human proteome (20,375 proteins, UniProt [3] version April 2022; excluding TITIN_HUMAN due to length). For these proteins, we obtained AlphaFold [4] structures from AlphaFoldDB [5] with an average per-residue confidence score (pLDDT) of more than 90%. This resulted in the 496 proteins of TMvis, as can be found in "TMvis496.fasta". The membrane embedding was predicted using the methods ANVIL [6], PPM3 [7], and per-residue TMbed predictions. As the three methods are based on different approaches, we decided to publish results for all. The figure “TMvis_project_overview.png” provides a graphical overview for each step described above.

TMvis Folder Structure: TMvis is separated into “alpha” containing predicted alpha-helical TMPs, and “beta” containing predicted beta-barrel TMPs. Within these folders, each protein is assigned one folder, identifiable by the respective unique UniProt ID. Each protein folder consists of: - “UniprotID.fasta” with UniProt ID, sequence, TMbed per-residue prediction - “AF-UniprotID-F1-model_v2.pdb” with the AlphaFold structure - “AF-UniprotID-F1-model_v2.cif” with the AlphaFold structure - “AF-UniprotID-F1-model_v2_ANVIL.pdb” with predicted ANVIL membrane embedding - “AF-UniprotID-F1-model_v2_ppm.pdb” predicted PPM3 membrane embedding

This dataset includes prediction pairs used for training random forest classifiers including SPOC, pairs used for 30 ranking experiments, all pairs that belong to the genome maintenance matrix on predictomes.org, and three proteome wide in-silico interaction screens conducted with human DONSON, human STK19, and human USP37. All pairs were generated with ColabFold v1.5.2. All our predictions used AF-M multimer version 3 weights models 1, 2, and 4 with 3 recycles, templates enabled, 1 ensemble, no dropout, and no AMBER relaxation. The Multiple Sequence Alignments (MSAs) (unpaired + paired) supplied to AF-M were generated by the MMSeqs2 server using default settings. Sequences run were generally capped at 3,600 amino acids total to avoid memory exhaustion on GPUs. ;

AlphaFold DB provides open access to over 200 million protein structure predictions to accelerate scientific research.

With the release of AlphaFold3, modeling capabilities have expanded beyond protein structure prediction to embrace the inherent complexity of biomolecular systems, including nucleic acids, ions, small molecules, and their interactions. The increased complexity of these assemblies is reflected in the input file generation process, presenting a significant hurdle for researchers without advanced computational expertise. While AlphaFold Server comes with a user-friendly graphical user interface, it supports only a subset of the features of AlphaFold3. To address this, we present af3cli, an open-source tool designed to facilitate the generation of AlphaFold3 input files, specifically tailored to the standalone version of AlphaFold3 and its unrestricted functionality. Featuring a user-friendly command-line interface and an accompanying Python library, af3cli simplifies the input generation process while maintaining flexibility and customization, which makes af3cli especially useful for fast (automated) generation of a large number of input files since it enables direct incorporation of FASTA files, keeps track of IDs, and validates the JSON file. Through practical examples, we demonstrate its capabilities for constructing input data for diverse biological structures, ranging from simple proteins to complex systems, and demonstrate its seamless integration into both manual and automated workflows.

Recent spectacular advances by AI programs in 3D structure predictions from protein sequences have revolutionized the field in terms of accuracy and speed. The resulting "folding frenzy" has already produced predicted protein structure databases for the entire human and other organisms' proteomes. However, rapidly ascertaining a predicted structure's reliability based on measured properties in solution should be considered. Shape-sensitive hydrodynamic parameters such as the diffusion and sedimentation coefficients (D0t(20,w),s0(20,w)) and the intrinsic viscosity ([η]) can provide a rapid assessment of the overall structure likeliness, and SAXS would yield the structure-related pair-wise distance distribution function p(r) vs. r. Using the extensively validated UltraScan SOlution MOdeler (US‑SOMO) suite, a database was implemented calculating from AlphaFold structures the corresponding D0t(20,w), s0(20,w), [η], p(r) vs. r, and other parameters. Circular dichroism spectra were computed u..., Production of this dataset required three major steps: collect the AlphaFold entries and additional metadata; prepare the structures for hydrodynamic, structural and CD calculations; and compute the hydrodynamic, structural and CD propertiesBriefly, each entry in the entire AlphaFold database was first compared with the corresponding entry in the UniProt database to find the (putative) initiator methionine, signal peptide and transit peptide regions, which were subsequently removed from the AlphaFold PDB files. Additional variants were created when propeptides were found. Potential disulfides were identified (subsequently allowing a better evaluation of the partial specific volume and of M) and written as SSBOND records in the cured PDBs, together with HELIX and SHEET information identified using the DSSP implementation in UCSF Chimera (Pettersen et al, 2004. Journal of computational chemistry, 25(13), pp.1605-1612). Batch-mode US-SOMO was then used to calculate the mass M, The translat..., This is a tar archive of all datasets for each AlphaFold entry. This includes a csv file containing all hydrodynamic parameters, a pdb file containing the cured pdb structure, an mmCIF file containing the cured pdb structure and a data file containing the circular dichroism spectrum, and a p(r) vs r dat file.Use "tar xf somoaf_all_data.tar" to extract the primary archive.This will result in 1,002,038 individual .txz file, each representing one UniProt accession code and containing 5 files.When propepties are identified and removed, the extracted file name will contain a -pp#, where # is a list of the propepties removed.For example, to extract the data from an individual txz file, use "tar Jxf xxxx.txz", where xxxx is replaced by the appropriate name containing the accession code.

The Deep Green list is based on the identification and curation of conserved unannotated proteins in three green lineage (Viridiplantae) model organisms; Arabidopsis thaliana, Chlamydomonas reinhardtii, and Setaria viridis. Preliminary characterization of Deep Green proteins and genes was done using various informatics tools and published data sets and is presented in Knoshaug, Sun, et al., 2023, submitted. The structures of these unannotated proteins were also predicted using AlphaFold (Jumper et al., 2021). The data deposited here are the AlphaFold structural predictions having the highest pLDDT score and thus identified as the best folded structure (ranked_0). These data enable others to do in-depth structural characterizations to aid in functional characterization leading to deeper understanding of plant biology.

This brief worksheet explains how to generate a protein structure of a mutant that is currently not in the PDB database. Using AlphaFold 3 and the wild-type sequence (uniprot or other resource), the mutant protein structure can be predicted in a variety of formats. In this example, the G551D mutation of CFTR, which influences ATP binding, is illustrated.
