Hemoglobin from the antarctic fish Notothenia coriiceps neglecta. Amino acid sequence of the beta chain.
1. Notothenia coriiceps neglecta is a cold-adapted notothenioid teleost, widely distributed in the Antarctic waters. 2. In comparison with fishes from temperate waters, the blood of this teleost contains a reduced number of erythrocytes and concentration of hemoglobin; the erythrocytes contain two hemoglobins, Hb1 and Hb2, respectively accounting for approximately 90, and 5% of the total. 3. The two components differ by the alpha chain; the amino acid sequence of the beta chain in common to the two hemoglobins has been established, thus completing the elucidation of the primary structure of the major component Hb 1.
