ResumoYAMAMOTO, O. Radiation-Induced Binding of Phenylalanine, Tryptophan and Histidine Mutually and with Albumin. Radiat. Res. 54, 398-410 (1973). Phenylalanine, tryptophan and histidine, in aqueous solution, can be bound to each other and to serum albumin when exposed to y-rays. The precipitation method with trichloroacetic acid was used to analyze the binding with albumin, and chromatography was used to analyze their binding with each other. During such radiationinduced binding of aromatic amino acids, the indirect participation of hydroxyl radicals from water was also observed using scavengers. It is proposed that this reaction may
