title: The primary structure of the hemoglobin of the electric eel (Electrophorus electricus).
abstract: The blood of the Electric Eel contains only one hemoglobin component. The primary structures of the alpha- and beta-chains are presented. These were separated by high-performance liquid chromatography, using a new kind of buffer system. The alpha-chains are acetylated, and consist of 142 residues, while the beta-chains are not blocked, and consist of 147 residues. The phylogenetic distances between these and the alpha- and beta-chains of human hemoglobin are 48 and 50% amino-acid exchanges, respectively. The relationship between primary structure and the Bohr effect and Root effect is discussed, especially the significance of the serine found in position F9 beta.
