A pleiotropic mutant of Bacillus subtilis was isolated which overproduced in the presence of glucose several enzymes whose synthesis is subject to glucose catabolite repression. Examination of intracellular metabolites suggested that the mutation may have resulted in a defect in glycolysis, increasing phosphoenolpyruvate and decreasing pyruvate, 2-ketoglutarate, and oxaloacetate.
分离出枯草芽孢杆菌的一个多效突变体,该突变体在葡萄糖存在的情况下过量产生几种其合成受葡萄糖分解代谢物阻遏的酶。对细胞内代谢物的检测表明,该突变可能导致糖酵解缺陷,增加磷酸烯醇丙酮酸并减少丙酮酸、2-酮戊二酸和草酰乙酸。
