Abstract

Yeast strains carrying recessive mutations representing four different loci that cause defects in pyruvate kinase, pyruvate decarboxylase, 3-phosphoglycerate kinase, and 3-phosphoglycerate mutase were isolated and partially characterized. Cells carrying these mutations were unable to use glucose as a carbon source as measured in turbidimetric growth experiments. Tetrad analysis indicated that these mutations were not linked to each other; one of the mutations, that affecting phosphoglycerate kinase, was located on chromosome III.

摘要

分离出了携带隐性突变的酵母菌株,这些突变代表了四个不同的基因座,它们分别导致丙酮酸激酶、丙酮酸脱羧酶、3-磷酸甘油酸激酶和3-磷酸甘油酸变位酶出现缺陷,并对其进行了部分表征。在比浊生长实验中,携带这些突变的细胞无法将葡萄糖用作碳源。四分体分析表明,这些突变彼此不连锁;其中一个影响磷酸甘油酸激酶的突变位于第三条染色体上。
