 Abstract    Protein synthesis after UV-and X-irradiation was investigated in diploid yeast. The incorpora­ tion of radioactively labelled lysine and phenylalanine was measured 2.5 and 4 hours after ex­ posure. 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.

 Title    Yields of 2-Deoxy-D-gluconic, D-Gluconic and Other Sugar Acids in Gamma-Irradiated Aqueous Solutions of D-Glucose  
 Abstract    H e r m a n n E s t e r b a u e r , J a c k S c h u b e r t , E d w a r d B. S a n d e r s , a n d Ch a r l e s C. S w e e l e y The yields of 2-deoxy-D-gluconic, D-gluconic and other sugar acids from 6 0 Co-gamma irradiated (dose rate = 4 Krads/min) D-glucose solutions are reported. The acids produced upon radiolyses were separated from glucose and neutral products by anion exchange, assayed by gas chromatography of the trim ethylsilyl derivatives, and definitive identification made by mass spectrometry. In He degassed, irradiated 0.055 M glucose G(2-deoxy-D-gluconic acid) = 0.62 and G(D-gluconic acid) = 0.20. The approximate G values for the other identified acids are: glyceric acid 0.03, 2-deoxy-tetronic acid 0.04, tetronic acid 0.03, 4-deoxypentonic acid 0.02, deoxyketogluconic acid 0.17. In N 20 saturated glucose solutions D-gluconic acid yields increased by a factor of ~ 1.9 while that of 2-deoxy-D-gluconic acid increased by a factor of only ~ 1.1.
