Abstract:Hemoglobin β chains were isolated from both the arctic ground squirrel (Citellus parryii undulatus) and the yellow-bellied marmot (Marmota flaviventris). After various enzymatic and chemical cleavages, the primary structures of these β chains were determined. Only one sequence difference was found between the yellow-bellied marmot β chain and that of the European marmot (Marmota marmota). Ground squirrels (C. p. undulatus, Citellus townsendii, and Citellus citellus) showed more species-related differences than… Show more
