Abstract: | The moderate evolution rate of apomyoglobins may be the support of a simplified strategy for determining unknown covalent structures within the order of Carnivora, taking the badger apomyoglobin as a model. The CNBr cleavage was followed by the isolation of three polypeptide fragments which were subsequently submitted to trypsin digestion. The fingerprints of the three hydrolysates as may be obtained from seven Carnivora species, show a fairly constant number of spots, often corresponding to identical or closely related peptides, espcially in the case of the N-terminal and C-terminal fragments. |
