Carnivora: the amino acid sequence of the adult European mink (Mustela lutreola, Mustelidae) hemoglobins.

The complete amino acid sequences of the hemoglobins from the adult European mink (Mustela lutreola) are presented. The erythrocytes contain two hemoglobin components and three globin chains. The isolation of globin chains achieved by ion-exchange chromatography on a column of CM-cellulose in 8 M urea buffer. The primary structure of globin chains and of the tryptic peptides determined in liquid- and gas-phase sequenators. The alignment of the alpha- and beta-chains with those of reported sequences from other carnivora species belonging to the family Mustelidae may give an insight into the evolution of this molecule.
