Gamma Irradiation of Polypeptides: Transformation of Amino Acids
The formation of aspartic acid from glutamic acid, aspartic and glutamic acids from proline, alpha -aminobutyric acid from methionine, aspartic acid from histidine, dihydroxyphenylalanine from tyrosine, tyrosine and dihydroxyphenylalanine from phenylalanine, alanine from cysteine and glycine from alanine was observed when aqueous solutions of the amino acids in the form of peptides or polyamino acids were irradiated. When poly-Lglutamic acid or poly-L- proline was irradiated in the presence of C/supo 14/-labeled NaHCO/sub 3/, the radioactive C was fixed by the aspartic and the glutamic acid.
