Fig. 3. (Top) Diagrammatic representation of the Fry-L protein with the five similarity regions labeled. In parentheses is the number of amino acids in that region of the Fry protein. Shown below the Fry protein is the percentage of identical amino acids in various Fry homologs. For each of these, the number of amino acids over which the similarity to Fry is seen is given in parentheses. Note for all of the proteins that contain the 4th region, it is approximately 110 amino acids. (Bottom) Amino acid sequence for Fry, CAB42442 and AAF99910 for the first similarity domain. We call this region the Fry domain. Similar amino acids are shaded and a consensus sequence is also shown.
