The globulins of cotton seeds XIX. Chymotryptic and tryptic peptides of subunit C of the 11S globulin

Summary 1. The structures of 51 chymotryptic peptides isolated from a chymotryptic hydrolyzate of subunit C have been determined.2. The structures of 15 tryptic peptides from a tryptic hydrolyzate of subunit C have been established.3. On the basis of the structures of the peptides, the structure of the molecule of subunit C of the 11S globulin of cotton seeds has been established.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

The globulins of cotton seeds XI. The structure of the chymotryptic peptides of the 7S globulin

Summary The amino-acid sequences of the chymotryptic peptides of the 7S globulin of cotton seeds have been determined.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

The globulins of cotton seeds XII. The structure of the 7S-globulin

Summary 1. The 7S globulin of cotton seeds consists of eight polypeptide chains of two types differing by their contents of carbohydrates and of amide groups.2. On the basis of the results of a study of the amino-acid sequences of the peptides obtained by cleaving the 7S globulin with trypsin and chymotrypsin, its complete primary structure has been put forward.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.
