Abstract

The complete primary structure of the .alpha.- and .beta.-chains of the hemoglobin of Malayan Sun Bear (Helarctos malayanus) is presented. After cleavage of the heme-protein link and chain separation by RP-HPLC, amino-acid sequences were determined by Edman degradation in liquid- and gas-phase sequenators. An interesting result of this work is the demonstration that the hemoglobin of Malayan Sun Bear is identical to the hemoglobins of Polar Bear (Ursus maritimus) and Asiatic Black Bear (Ursus tibetanus). The paper gives an updated table of identical hemoglobin chains from different species. This paper may be considered as a compilation of work on the genetic relationship of Pandas.
