AlphaFold 2: Solving the Protein Folding Problem

AlphaFold 2, developed by DeepMind, has successfully solved the long-standing protein folding problem. Proteins are essential to all life and understanding their 3D structure is crucial for determining their function and developing drugs. The traditional methods of experimental biology are time-consuming and expensive. AlphaFold 2 uses AI algorithms to predict the 3D structure of proteins from their amino acid sequence, significantly accelerating the process. The system combines over 30 component algorithms and incorporates constraints from physics and biology to enhance accuracy. Despite the relatively small training set of protein structures, AlphaFold 2 produces predictions in a matter of seconds, revolutionizing structural biology and drug development.
