BFVD v3 expands viral protein structure predictions to 5.8 million

BFVD v3 expands the Big Fantastic Virus Database to 5,776,417 predicted viral protein structures, a 16.4-fold increase over v2. Released September 15, 2026, it covers individual viral sequences from UniProt 2025_03 and provides downloadable structures, metadata and a Foldseek-searchable database under CC BY 4.0. It supports viral protein structure comparisons, including phage research; these are computational predictions, not experimentally determined structures.
