Figure 7: Alignment of hemoglobin sequences from deep-sea polynoids.

From: Adaptation and evolution of deep-sea scale worms (Annelida: Polynoidae): insights from transcriptome comparison with a shallow-water species

Figure 7

The sequences with a blue background are tetra-domain hemoglobins from three species of Branchipolynoe. Green letters above sequences indicate the positions of the heme pocket residues in tetra-domain hemoglobin. Red letters indicate the positions of conserved amino acid residues in all hemoglobin domains. Black letters show the positions of conserved amino acids in all hemoglobins from deep-sea polynoids. Orange letters show the positions of conserved amino acids in tetra-domain hemoglobins. The asterisks show positive selected sites in tetra-domain hemoglobins. SD: single-domain; TD: tetra-domain; Bse: B. seepensis; Bsy: B. symmytilida; Bpe: B. pettiboneae; Lepw: Lepidonotopodium williamsae; Branchipc: Branchiplicatus cupreus; Branchins: Branchinotogluma segonzaci; Branchint: Branchinotogluma trifurcus.
