Abstract: | 13 peptic peptides have been isolated from the insoluble (at pH 5.0) fraction of the tryptic hydrolysate of main chromatographic component of otter myoglobin and their amino acid composition and N-terminal amino acid sequences have been determined. The isolated peptides contain in total 40 amino acid residues. The results obtained, along with those on tryptic peptides and the comparison with homologous portions of myoglobins of the known primary structure, allowed reconstructing the complete amino acid sequence of otter myoglobin. |
