Fig. 2. Comparison of the fruit fly and mosquito leucokinin peptides. The sequences
of the Drosophila melanogaster (Drosophila leucokinin),
Aedes aegypti (Aedes leucokinin), Culex salinarius
(Culex leucokinin) and Anopheles gambiae (Anopheles
leucokinin) leucokinin peptides are compared. Residues conserved with
Drosophila leucokinin are indicated in bold. Analysis of the D.
pseudoobscura genome sequence suggests that a single leucokinin identical
to that of D. melanogaster is encoded.
