Abstract
Extracellular d-fructose was metabolized preferentially over intracellular d-fructose in growing cells of a d-fructokinaseless mutant of Aerobacter aerogenes. This finding is interpreted to indicate that phosphorylation of d-fructose by the membrane-bound phosphoenolpyruvate: d-fructose 1-phosphotransferase system in intact cells is coupled to unidirectional transport.
摘要
在产气气杆菌的一个无d-果糖激酶突变体的生长细胞中，细胞外的d-果糖比细胞内的d-果糖更优先被代谢。这一发现被解释为表明完整细胞中膜结合的磷酸烯醇丙酮酸：d-果糖1-磷酸转移酶系统对d-果糖的磷酸化与单向运输相偶联。
