Amino Acid Strand (IMAGE) Stanford University Caption Proteins are made of strings of amino acids that resemble the strand in the image above. Using machine learning models, researchers were able to design the identity of amino acids on a computer to engineer protein enzymes that make pharmaceuticals. The molecule at the center of the image above is an engineered McbA enzyme. Credit Justin Muir Usage Restrictions Please use with credit.
