Investigation of the globulins of cotton seeds VII. Peptides of a triptic hydrolyzate of the 7S-globulin

  • 17 Accesses

Summary

1. The peptides of a tryptic hydrolyzate of the 7S-globulin have been isolated and characterized.

2. The glycopeptide of subunit II has been isolated and its amino-acid and carbohydrate compositions have been determined.

3. It has been shown that the main difference in the subunits of the 7S-globulin consists in the presence of an oligosaccharide in the C-terminal peptide of subunit II.
