The amino acid sequence of the alpha chain of HB 2 completes the primary structure of the hemoglobins of the Antarctic fish Notothenia coriiceps neglecta.
1. The blood of Notothenia coriiceps neglecta (a cold-adapted notothenioid fish, widely distributed in Antarctic waters, and characterized by a relatively low content of erythrocytes and hemoglobin), contains two hemoglobin components, Hb 1 and Hb 2; the amino acid sequences of the beta chain of Hb 1 and Hb 2 are identical. 2. The amino acid sequence of the alpha chain of Hb 2 has been established, thus completing the elucidation of the primary structure of the two hemoglobins.
