Artificial intelligence has worked out the structures of 200 million proteins (that’s practically all of them)

The artificial intelligence group DeepMind has unraveled the structures of nearly every protein known to science.

Researchers achieved the feat using the program AlphaFold, which DeepMind first developed in 2018 and released publicly in July 2021. The open-source program can predict a protein’s 3D structure from its sequence of amino acids, the building blocks that make up proteins. A protein‘s structure dictates its functions, so the database of 200 million protein structures identified by AlphaFold has the potential to help identify new protein workhorses that humans can make use of.
