Activation of plasma membrane ATPase by the addition of glucose was examined in several cell division cycle mutants of Saccharomyces cerevisiae. The start mutant carrying the cdc25 mutation was shown to be defective in ATPase activation at the restrictive temperature. Genetic analysis showed that lack of growth and defective activation of ATPase at the restrictive temperature were caused by the same mutation. It was also found that CDC25 does not map at the same locus as the structural gene of plasma membrane ATPase (PMA1). We conclude that the product of CDC25 controls the activation of ATPase.
在酿酒酵母的几个细胞分裂周期突变体中,研究了添加葡萄糖对质膜ATP酶的激活作用。携带cdc25突变的起始突变体在限制温度下的ATP酶激活存在缺陷。遗传分析表明,在限制温度下生长缺陷和ATP酶激活缺陷是由同一突变引起的。还发现CDC25与质膜ATP酶(PMA1)的结构基因不在同一基因座上。我们得出结论,CDC25的产物控制着ATP酶的激活。
