[Hemoglobin of the golden eagle (Aquila chrysaetos, Accipitriformes): amino acid sequence of the alpha A- and beta chains of the principal component].

: The primary structures of the alpha A- and beta-chains from the major hemoglobin component of Golden Eagle (Aquila chrysaetos) are given. By homologous comparison, Greylag Goose (Anser anser) hemoglobin and Golden Eagle alpha A-chains differ by 17 amino acids or 19 nucleotides (2 two-point mutations), beta-chains by 9 exchanges. Five substitutions have modified alpha 1 beta 1-contacts, one substitution, one alpha 1 beta 2-contact and one alpha 1 alpha 1-contact. Differences by homologous comparison to other hemoglobins of birds are discussed.
