The Primary Structures and Functional Properties of the Major and Minor Hemoglobin Components of the Adult White-Headed Vulture (Trigonoceps occipitalis, Aegypiinae)*

,Summary:The primary structures of the hemoglobin components Hb A and Hb D of White-Headed Vul­ ture (Trigonoceps occipitalis) are presented. The glo­ bin chains were separated on CM-Cellulose in 8M urea buffer, the components by FPLC in phosphate buffers. The amino-acid sequences were established by automatic Edman degradation of the globin chains and of the tryptic peptides in liquid phase and gas­ phase sequenators. The sequences differ from those of European Black Vulture by only one mutation in the ",A-chains (a137). The aD-chains and the fl-chains are identical. This means that for the first time identi
