Abstract

Tauro, Patric (The University of Wisconsin, Madison), and Harlyn O. Halvorson. Effect of gene position on the timing of enzyme synthesis in synchronous cultures of yeast. J. Bacteriol. 92:652-661.-In synchronously growing cultures of Saccharomyces cerevisiae, enzyme synthesis is periodic. The effect of various factors on the timing of alpha-glucosidase synthesis has been investigated. The period of the cell cycle during which alpha-glucosidase is synthesized is unaffected by the method employed to induce synchrony, as well as other environmental conditions. However, a definite relationship exists between the number of nonallelic structural genes present for alpha-glucosidase and the number of periods of synthesis during the cell cycle. It is concluded that the periodic synthesis of enzymes observed in synchronously growing cultures of yeast is probably the result of an ordered process of transcription of the various structural genes.

摘要

陶罗,帕特里克(威斯康星大学麦迪逊分校)和哈林·O·哈尔沃森。基因位置对酵母同步培养物中酶合成时间的影响。《细菌学杂志》92:652 - 661。——在酿酒酵母的同步生长培养物中,酶的合成是周期性的。已经研究了各种因素对α - 葡萄糖苷酶合成时间的影响。α - 葡萄糖苷酶合成所在的细胞周期阶段不受用于诱导同步化的方法以及其他环境条件的影响。然而,α - 葡萄糖苷酶存在的非等位结构基因数量与细胞周期中合成周期的数量之间存在明确的关系。得出的结论是,在酵母同步生长培养物中观察到的酶的周期性合成可能是各种结构基因有序转录过程的结果。
