title: The amino-acid sequence of alpha A- and beta-chains from the major hemoglobin component of American flamingo (Phoenicopterus ruber ruber).
abstract: The complete amino-acid sequence of alpha A- and beta-chains from the major hemoglobin component (HbA) of American Flamingo ( Phoenicopterus ruber ruber) is presented. The minor component (HbD) with alpha D-chains was detected in similar amounts (25%) as in chicken and pheasant hemoglobins. The comparison of American Flamingo and Greylag Goose (Anser anser) hemoglobins shows that alpha A-chains differ by 22 exchanges and beta-chains by only 4 exchanges. Two substitutions modify alpha 1 beta 1-contacts. Amino-acid replacements between American Flamingo and other bird hemoglobins are discussed.
