The activities of the key enzymes of the glyoxylic acid pathway, isocitrate lyase and malate synthetase are 2.6 and 2.8 times of those the control culture. 乙醛酸循环关键酶,异柠檬酸裂解酶和苹果酸合成酶分别为正常尿素培养物的2.6和2.8倍。
Glucose-6-phosphate dehydrogenase, citrate synthase, isocitrate lyase and malate synthetase are the four key enzymes involved in the primary metabolism. 其中,酶学水平上,比较了两菌株在初级代谢过程中的四种关键酶酶活,分别是葡萄糖-6-磷酸脱氢酶、柠檬酸合成酶、异柠檬酸裂解酶和苹果酸合成酶。
