Abstract
Tobacco phosphoenolpyruvate carboxylase (PEPC) [EC 4.1.1.31] cDNA was efficiently expressed in E. coli under the control of the lacZ promoter. The enzyme, purified to homogeneity, had the same catalytic activity, and was phosphorylated in vitro by maize PEPC kinase.
摘要
烟草磷酸烯醇式丙酮酸羧化酶（PEPC）[EC 4.1.1.31]的cDNA在乳糖操纵子启动子的控制下于大肠杆菌中高效表达。该酶纯化至同质，具有相同的催化活性，并在体外被玉米PEPC激酶磷酸化。
