The Escherichia coli K-12 ackA gene, which encodes an acetate kinase, was cloned. The acetate kinase activities of ackA+ plasmid-containing strains were amplified 160- to 180-fold. The complete nucleotide sequence of the ackA gene was determined. It was deduced that the ackA gene coded for a protein of 400 amino acids with an Mr of 43,297. The ackA gene was found to be located about 15 kilobases upstream of the purF-folC-hisT region of the chromosome.
编码乙酸激酶的大肠杆菌K-12 ackA基因被克隆。含有ackA+质粒的菌株的乙酸激酶活性增强了160至180倍。测定了ackA基因的完整核苷酸序列。据推断,ackA基因编码一种由400个氨基酸组成、分子量为43297的蛋白质。发现ackA基因位于染色体上purF-folC-hisT区域上游约15千碱基处。
