All Models and Alignments: d_melanogaster_2017.tar
Summary table: d_melanogaster_2017.summary.txt
The summary table lists all models by ModBase seq_id (unique for a given sequence), ModBase model_id (unique for a given model) and database_id (the primary identifier for the sequence for which the model was built, with a suffix since multiple models may exist for a single sequence).
Models are provided in PDB format. If you prefer mmCIF files, you can use the modbase_pdb_to_cif.py script from the modbase_utils GitHub repository to generate them. ModBase mmCIF files are compliant with the PDBx and ModelCIF mmCIF dictionaries.
