Google’s DeepMind division has rolled out a few fascinating and impressive AI models, including one that can play StarCraft II better than you (and almost anyone else). DeepMind isn’t only interested in AI to play games though. Last year, the company unveiled AlphaFold, a machine learning model that can predict the shape of proteins. Now, DeepMind has announced that it has generated structures for all 200+ million proteins in the centralized UniProt database. This is a big deal for basic biological research as well as for efforts to tackle some of the most important scientific conundrums of our time.

Proteins are the basis of all biological life on Earth, but even if you know the amino acid sequence of a protein, that doesn’t mean you know what it does or how it works. The sequence of a protein gives it patterns of positive and negative charges, hydrophilic and hydrophobic regions, and cross-linked segments. This is what determines the protein’s active shape, or “conformation” as it’s known in the lab, and a protein’s conformation is what gives it its function. Even a few mistakes in the structural prediction can be the difference between an enzyme…
