A List of the proteins studied along with the numbers of amino acids in each of them (L), the number of sequences (N) available for the coevolutionary analysis in each of them, the sequence to length ratio (N/L), and the precision (P) of the contact prediction for each of them, as defined in Equation 8. N/L = 5 is often used as a guideline for the minimum number of sequences required to carry out an accurate coevolutionary analysis. The list is sorted in descending order of N/L. The fold of the protein is given along with its full name and function, if known.
