AlphaFold code

DeepMind and Google have created a method to access the code on GitHub. All the details to install AlphaFold locally are on the "readme" page, visible on the lower portion of the GitHub page ColabFold (See my Blog: Google colab is a free cloud notebook environment).

AlphaFold background

Predicting protein three-dimensional (3D) structures given a linear sequence of amino acids. The AlphaFold2 breakthrough.

Computing residues per turn in an alpha helix

Single mutation to be modeled I recently had an interesting challenge, that of creating a molecular model of a protein expressed from a gene with a newly identified single amino acid mutation. I (wrongly) assumed that it would be a “simple” 3D homology modeling problem, solved by common methods. It turns out that the protein …

Protein Backbone from alpha-Carbon

Building a Protein Backbone from alpha-Carbon Files containing only C-alpha ATOM records can be the result of modeling but can also be a step in structure resolution. Theoretical models are now deposited in the ModelArchive(*). How can we obtain a complete structure for further investigation, e.g. to use in a molecular graphics software? Using Sybyl? In …

Wayback Machine – finding lost web pages

Summary There is a vast archive of free content on the Internet Archive and web pages and documents preserved since about 1996 on the Wayback Machine that allows finding and retrieving web pages and documents that have vanished from the every day web and are not indexed in the search engines. An example is provided. Vanishing content …

VMWare and EFI partition

I have been a Macintosh user since 1986 but it is still necessary once in a while to access a Windows system and that is why VMWare Fusion is installed on my iMac which has a separate partition on its drive called BootCamp that contains the Windows system. There are different ways to set-up using …

Do yourself a favor: learn Markdown – Episode 4. Reproducible reports

The message The essential message is this: stop using Copy/Paste from one program to another (e.g. a chart from Excel to Word) as this is a manual process that is not reproducible and can easily get out of sync if new data need to be incorporated and the report reconstructed anew. The solution is to …
