The complete amino acid sequence of the .alpha. chain of the main hemoglobin of the Antarctic fish Notothenia coriiceps neglecta (family Nototheniidae) has been determined. It consists of 142 residues; an acetylated seryl residue is at the amino terminal. The molecular mass is 15519 Da. In comparison with .alpha.-chain sequences of non-Antarctic poikilothermic fish hemoglobins, the homolgy appears to be significantly lower than that existing among the latter species. A higher homology has been found with the .alpha.-chain sequence of the non-poikilothermic bluefin tuna.

Abstract
The complete amino acid sequence of the .alpha. chain of the main hemoglobin of the Antarctic fish Notothenia coriiceps neglecta (family Nototheniidae) has been determined. It consists of 142 residues; an acetylated seryl residue is at the amino terminal. The molecular mass is 15519 Da. In comparison with .alpha.-chain sequences of non-Antarctic poikilothermic fish hemoglobins, the homolgy appears to be significantly lower than that existing among the latter species. A higher homology has been found with the .alpha.-chain sequence of the non-poikilothermic bluefin tuna.File in questo prodotto:
