Physicochemical properties of protease A from cotton seeds
- 19 Downloads
It has been found that protease A from dormant seeds of cotton plants of the Tashkent-1 variety consists of two subunits: α and β, differing in molecular weight and carbohydrate content and linked with one another by a disulfide bridge. The amino acid and carbohydrate compositions of the enzyme and its subunits have been determined. A comparative study of peptide maps of protease A and its α- and β-subunits and of their amino acid compositions has permitted the assumption that subunits α and β, in their turn, each consists of two polypeptide chains that are identical or very close in composition.
