Abstract
The extrachromosomal psi+ determinant in the yeast Saccharomyces cerevisiae enhanced the expression of Mendelian UAA suppressors by 6- to 10-fold. The psi+ determinant by itself is a weak UAA suppressor that caused the production of approximately 1% of the normal level of iso-1-cytochrome c in a strain containing the UAA mutation cycl-72.
摘要
酿酒酵母中的染色体外psi+决定簇使孟德尔UAA抑制子的表达增强了6至10倍。psi+决定簇本身是一个弱UAA抑制子，在含有UAA突变cycl-72的菌株中，它导致产生的异-1-细胞色素c约为正常水平的1%。
