In the yeast Saccharomyces cerevisiae, the sugar-induced expression of various genes coding for glycolytic enzymes is triggered by increases in the concentrations of different internal metabolites. Here, we show that the induction of the glycolytic isoenzyme enolase 2 is strictly dependent on the abilities of different mutant strains to increase the level of glucose-6-phosphate after the addition of sugars. In contrast, the induction of alcohol dehydrogenase I is dependent on increasing concentrations of metabolites in the late stages of glycolysis.
在酿酒酵母中,编码糖酵解酶的各种基因的糖诱导表达是由不同内部代谢物浓度的增加引发的。在这里,我们表明糖酵解同工酶烯醇化酶2的诱导严格依赖于不同突变菌株在添加糖后提高6-磷酸葡萄糖水平的能力。相比之下,乙醇脱氢酶I的诱导依赖于糖酵解后期代谢物浓度的增加。
