Figure 5From: Chemosensory genes identified in the antennal transcriptome of the blowfly Calliphora stygia Ligand-binding S1 and S2 domains. Important glutamate-interacting residues are lacking in the ligand binding domains of most C. stygia IR candidates. MAFFT amino acid alignments of the S1 (A) and part of S2 (B) ligand binding domains of candidate C. stygia IRs and Drosophila melanogaster IRs and iGluRs. The key binding residues in iGluRs are boxed.Back to article page
