The Primary Structure of the Hemoglobin of Spectacled Bear(Tremarctos ornatus,Carnivora)

Biological Chemistry Hoppe-Seyler, 1987
The complete primary structure of the alpha- and beta-chains of the hemoglobin of Spectacled Bear (Tremarctos ornatus) is presented. Following cleavage of the heme-protein link and chain separation by RP-HPLC, their amino-acid sequences were determined by Edman degradation in liquid- and gas-phase sequenators. The hemoglobin of Spectacled Bear displays
