^aMean number of amino acids comprising the two polypeptide chains representing each protein family.
^bNumber of amino acid residue matches. Parentheses contain the percentage of matched residues utilized out of the total (mean) number of amino acids. Due to length differences between proteins, it is not possible to reach 100% residue matches.
^cIsocitrate Dehydrogenase.
^dHemopexin Repeats.
