BgirFold is a protein structure prediction tool that takes the amino acid sequence to be predicted as input and outputs the all-atom 3D structure corresponding to the amino acid sequence. The key components of BgirFold are Evoformer Module and Structure Module from AlphaFold2. The difference compared to AlphaFold2 is that our BgirFold optimizes the search process of multiple sequence alignments while capturing as many available homologous templates as possible. The current version is trained on PDB data before the maximum release date of 2021-12-20 .
