Introductions to AlphaFoldIntroductions to AlphaFold

• AlphaFold. An introduction and overview.
• Theoretical models describes the breakthrough in structure prediction made by AlphaFold in CASP 14 (2020) and the continued pre-eminence of AlphaFold in CASP 15 [2022].

How To Make PredictionsHow To Make Predictions

• How to predict structures with AlphaFold when the AlphaFold Database does not already have what you want.
• Joining AlphaFold predictions for halves of a molecule, when the sequence is too long for AlphaFold to handle.
• How to renumber PDB files in order to correct sequence numbers.

Interpreting PredictionsInterpreting Predictions

• AlphaFold pLDDT and expected distance error
• Calculating GDT TS the Global Distance Test Total Score, one of the metrics used for judging accuracy of predictions in the CASP competitions.
• AlphaFold3 case studies includes a case that AlphaFold3 cannot predict.

Examples of PredictionsExamples of Predictions

• AlphaFold2 examples from CASP 14. A detailed analysis of several AlphaFold predictions compared with empirically-determined structures.
• AlphaFold3 case studies (November 2024) includes a case that AlphaFold3 cannot predict.

Uses of PredictionsUses of Predictions

• Missing residues and incomplete sidechains suggests using AlphaFold predicted structures, in parallel with empirical models that have missing residues or atoms, when analyzing surface characteristics such as charge distribution (electrostatic potential maps), salt bridges, cation-pi interactions, etc.
