Alignment of the three cuttlefish haemocyanins (SoH1-SoH3). Highlighted are the characteristic six histidine residues forming the oxygen binding sites (green), one thioether bridge, three disulphide bridges and the potential glycosylation sites predicted with NetNGlyc1.0. The secondary structure of the FUg of E. dofleini (Cuff et al., 1998) is displayed on the bottom.
