Protein synthesis and amino acid pools in irradiated yeast cells.
Protein synthesis after UV- and X-irradiation was investigated in diploid yeast. The incorporation of radioactively labelled lysine and phenylalanine was measured 2.5 and 4 hours after exposure. By varying the specific activity the pool sizes could be estimated. At 2.5 hours there is some increase in pool sizes and a dose-dependent enhancement of protein synthesis. At 4 hours pools are again normal, but the increase of synthetic activity prevails.
