title: Amino acid sequence of alpha-chain of hemoglobin IV from trout (Salmo irideus).
abstract: The amino acid sequence of the alpha-chain of trout hemoglobin (Hb) IV is given, thus completing the primary structure of the hemoglobin component of trout's blood characterized by the Root effect. The trout Hb IV alpha-chain consists of 142 amino acid residues; comparison with the corresponding sequences from human and carp hemoglobins shows differences of 50.0 and 35.9%, respectively. A difference of 39.6% is found with the alpha-chain of trout Hb I, the other major hemoglobin component of trout blood, devoid of heterotropic effects.
