Can alphafold predict disulfide bonds
WebHere, we describe a method to predict pairs of protein residues that can be mutated to form a disulfide bond. We combine a physics-based approach that incorporates implicit … WebAlphaFold is trained on protein chains in the PDB released before 2024-04-30. Predictions can also make use of up to 4 templates released before 2024-02-15. However, templates are not a critical input for AlphaFold to make an accurate prediction; the model can make a strong prediction based on a multiple sequence alignment alone.
