Fig. 4.

(A) Sequence alignment of Td18-like proteins from Panstrongylus chinai (Pc13, Pc15, Pc58 and Pc59) together with Td18 from Triatoma dimidiata (accession number: BAI50824). Black-shaded amino acids represent identical amino acids and gray-shaded amino acids represent conserved amino acids. Dashes indicate gaps introduced for maximal alignment. Asterisks at the top of the amino acids denote conserved cysteine residues, and the GXW motif is indicated by ###. (B) Phylogenetic tree analysis of Td18-like proteins from P. chinai (Pc13, Pc15, Pc58 and Pc59) together with Td18 from T. dimidiata. The numbers in parentheses indicate the number of transcripts of each contig. The scale bar represents 0.05% divergence. Bootstrap values are shown above branches.
