A gcr2 null mutant of Saccharomyces cerevisiae grows well on glucose in spite of its lower level of glycolytic enzymes between triose phosphates and pyruvate. A quantitative analysis shows that these levels are adequate to the flux but glycerate phosphates are elevated.
酿酒酵母的gcr2基因缺失突变体尽管在磷酸丙糖和丙酮酸之间的糖酵解酶水平较低,但在葡萄糖上仍能良好生长。定量分析表明,这些水平足以满足通量,但磷酸甘油酸水平升高。
