Tyrptic peptide compositions of hemoglobins from mink (Mustela vison) and hyena (Hyaenae hyaenae) and the alpha-chain of coatimundi (Nasua nasua).

The amino acid composition of the tryptic peptides from hyena hemoglobin, two hemoglobins of the mink and the alpha-chain of coatimundi have been determined, allowing comparison with data previously obtained from other carnivores. The two hemoglobins of mink differ at only one amino acid residue, alpha 15, which is glycyl in one hemoblobin and aspartyl in the other.
