Abstract

We report the cloning of the pykA and pykF genes from Escherichia coli, which code for the two pyruvate kinase isoenzymes (ATP:pyruvate 2-O-phosphotransferases; EC 2.7.1.40) in this microorganism. These genes were insertionally inactivated with antibiotic resistance markers and utilized to interrupt one or both pyk genes in the E. coli chromosome. With these constructions, we were able to study the role of these isoenzymes in pyruvate biosynthesis.

摘要

我们报道了从大肠杆菌中克隆出pykA和pykF基因，这两个基因编码该微生物中的两种丙酮酸激酶同工酶（ATP：丙酮酸2-O-磷酸转移酶；EC 2.7.1.40）。这些基因用抗生素抗性标记进行插入失活，并用于中断大肠杆菌染色体中的一个或两个pyk基因。利用这些构建体，我们能够研究这些同工酶在丙酮酸生物合成中的作用。
