FIGURE 2.

Multiple sequence alignment of the three types of hemoglobin from L. pectinata, the bivalve mollusk S. inaequivalvis, and domain one of the nematode A. suum hemoglobin. The corresponding helices as predicted by the program suite iMoltalk applying the STRIDE method are labeled (red squares). Conserved residues are shaded in cyan and residues at position B10 (Tyr³⁰ in L. pectinata), E7 (Gln⁶⁵ in L. pectinata), Lys⁹² and Arg¹⁰⁰ (L. pectinata) are shaded in yellow. The gaps are labeled in green.
