Amino-acid sequence of the alpha D- and beta-polypeptide chains of the Japanese quail hemoglobin.
Two hemoglobin components are recognized in the erythrocytes of the adult Japanese quail: a major (Q-II) and a minor (Q-I) component. We have determined the amino-acid sequence of the alpha D-globin of the minor component and the beta-globin which is common to both components by conventional protein sequence analysis. The sequences of both the alpha D- and the beta-globins showed close homology with those of their counterpart constituents in other avian hemoglobins. Proline at position 119 in the alpha D-globin which is known to be critical for the altitude respiration by the alpha 1 beta 1 interface is conserved in the Japanese quail hemoglobin.
