Phosphofructokinase (pfkA) mutants of Escherichia coli are impaired in growth on all carbon sources entering glycolysis at or above the level of fructose 6-phosphate (nonpermissive carbon sources), but growth is particularly slow on sugars, such as glucose, which are normally transported and phosphorylated by the phosphoenolpyruvate, (PEP)-dependent phosphotransferase system (PTS).
大肠杆菌的磷酸果糖激酶(pfkA)突变体在所有进入糖酵解且处于或高于6-磷酸果糖水平的碳源(非允许碳源)上生长受损,但在诸如葡萄糖等通常由磷酸烯醇式丙酮酸(PEP)依赖性磷酸转移酶系统(PTS)转运和磷酸化的糖类上生长尤为缓慢。
