Caption: Studying related proteins, researchers identified pairs of amino acid residues (left) that seemed to change in lockstep in the evolutionary record. These co-varying pairs indicated points on protein (middle) likely to be in contact after folding, giving researchers enough clues to create a computational model of the protein's three-dimensional structure (right).
