[Hemoglobins, XLVIII: the primary structure of hemoglobin of the Indian elephant (Elephas maximus, Proboscidea): beta 2 = Asn].

[Article in German]


The primary structure of the hemoglobin of the Indian Elephant (Elephas maximus) is given. The sequence was determined automatically in a sequenator. By homologous comparison with adult human HbA, the alpha-chains differ by 24 exchanges and the beta-chains by 27 exchanges. Furthermore, we report p(O2)50 values with regard to altered contact sites with 2,3-bisphosphoglycerate in Indian elephant hemoglobin. Our findings explain the low p(O2)50 and the reduced interaction with 2,3-bisphosphoglycerate. Elephant hemoglobin has, like that of the Llama, only five phosphate binding sites. In addition, we have made an attempt to relate these results to aspects of respiratory physiology. Some implications of these biochemical and physiological results, concerning the Second Punic War and Hannibal's Alp transition, are given.
