The sequence of the amino acids – which is encoded in DNA – defines the protein’s 3D shape. The shape determines its function. If the structure of the protein changes, it is unable to perform its function. Correctly predicting protein folds based on the amino acid sequence could revolutionize drug design, and explain the ...
