Fig. 2. (A) ClustalW analysis of yellow-related proteins from different Diptera, including Phlebotomus papatasi salivary proteins, Aedes aegypti dopachrome converting enzyme, Anopheles gambiae and the three yellow-related proteins found in the salivary gland cDNA library of Lutzomyia longipalpis. Reverse-shaded amino acids represent identical amino acids among all these proteins; gray-shaded amino acids represent identical amino acids among phlebotomine yellow-related proteins. (B) Dendrogram of the yellow-related proteins indicating the distribution of three distinct clades. Bootstrap values are indicated in their respective nodes.
