If its structure has already been predicted there, download it, and skip to Interpreting Results below.

Such attempts require special maneuvers that are beyond the scope of the following instructions.įirst, check the AlphaFold Database for the protein of interest. It is less successful predicting homo- or hetero-complexes. See CAUTION provided by the AlphaFill team.ĪlphaFold performs best with single chains, which may include one or a few domains. Simply download the prediction from the Database.Īlso check the AlphaFill Database, which has added ligands to appropriate AlphaFold predictions. If your protein is there, you don't need to proceed with the instructions below. Structure predictions for over 300,000 proteins are already available in the AlphaFold Database. Some of the options recommended below were gleaned from the 1 hour 46 minute video of presentations by Sergey Ovchinnikov and Martin Steinegger (August, 2021) for the Boston Protein Design and Modeling Club We recommend the 'advanced' Colab by Sergey Ovchinnikov, Milot Mirdita and Martin Steinegger. enable users to submit sequences via web browser, executing the code in the Google cloud, using space private to each user, returning predicted structures.īelow are instructions for beginners who wish to predict structures. Subsequently, several Colabs became available offering free structure prediction for user-submitted protein sequences. In July, 2021, DeepMind released AlphaFold as open source code. For an overview, see Theoretical models, bearing in mind 'The Joys and Perils of AlphaFold'. Their success in the blind CASP competition astonished many experts.

In 2020, the AlphaFold project of Google's DeepMind team demonstrated a major breakthrough in predicting protein structure from sequence.
