Design of the Ubx/AbdA chimeras. (A) The AbdA and Ubx proteins are divided in five portions designated N-ter, NterC, HD, CterC, and C-ter. Dashes indicate conserved residues between Drosophila melanogaster Ubx and AbdA proteins. *, Identities, and :, similarities between D. melanogaster and Tribolium castaneum AbdA proteins. (B) Diagrams of Ubx/AbdA chimeric proteins. Dotted boxes represents AbdA sequences. The numbers in parentheses from chimeras A–F refer to the amino acids that have been changed to those found in equivalent position in AbdA.
