Profile scores for designed and  natural sequences

Distributions of profile scores for designed and natural sequences in engrailed and homeobox family proteins: The sequences designed on the template backbone are shown in dark. The natural sequences of the protein family to which the template structure belonged are shown in gray. The line arrow head indicates the profile score of the native sequence of the template structure. The solid arrow head indicates the profile score of the sequence designed by (Raha K, Wollacott AM, Italia MJ, Desjarlais JR. Prediction of amino acid sequence from structure. Protein Sci. 2000; 9:1106–1119).
