Summary “Explore how David Baker, Demis Hassabis, and John Jumper won the 2024 Nobel Prize in Chemistry for their advances in computer-assisted protein design.” Video: How AI Cracked the Protein Folding Code and Won a Nobel Prize This 22min19 video provides a very good explanation of the origins of the research in protein structure, from …
Summary Run the ColabFold version of AlphaFold2 on your laptop (slow without GPU) or on a large Linux cluster. The full tutorial with scripts is located at ColabFold with HTCondor What is AlphaFold2 Excerpt from a previous post (Five ways to run AlphaFold) AlphaFold can accurately predict 3D models of protein structures by providing an …
Summary We run a script to compute the distance between 2 atoms in a series of PDB files with identical molecules in different conformations and save the distance results into a plain text file. No GUI PyMOL In previous posts I explained how we can use PyMOL as a command-line tool from a Terminal when …
Summary Compute biological assembly from coordinates with a python script. Symmetry X-ray crystallography solved the mathematical problem to provide 3D (cartesian) coordinates but the resulting “asymmetric unit cell” does not necessarily represent the biological structure. The Protein Data Bank (PDB) now provides options to download the biological entity, which can contain a lesser number than …
Computational Modeling This is the general title of a new Tutorials pull-down menu that will be populated with new or updated tutorials. It can be found within the Tutorials menu list as Computational Modeling The very first tutorial is the result of an update to a Rosetta tutorial for “ligand docking” and adapt the Linux-based …
Summary Combine software and scripts on Docker and local macOS computer (Intel amd64 or arm64 Silicon Chip M series) to follow successfully the Rosetta tutorial Ligand Docking with a G-Protein Coupled Receptor. This method will allow to access the native OS speed while fulfilling all preparatory and exploratory steps that fail or are too complex …
