从大肠杆菌中克隆到天冬氨酸转氨酶基因。coli(aspC)亚克隆到M13噬菌体中,用合成的寡核苷酸引物,采用桑格双脱氧法进行测序。使用定点诱变技术构建突变基因,其中与磷酸吡哆醛形成席夫碱的赖氨酸的密码子被编码丙氨酸的密码子取代。突变基因在Tac启动子的控制下表达,以过量产生缺乏酶活性的突变蛋白。
The gene for aspartate aminotransferase from E. coli (aspC) was subcloned into M13 phage and sequenced using the Sanger dideoxy method with synthetic oligonucleotide primers. A mutant gene was constructed using sitedirected mutagenesis techniques in which the codon for the lysine that forms the Schiffs base with pyridoxal phosphate was replaced with one coding for alanine. The mutant gene was expressed under control of the Tac promoter to overproduce a mutant protein lacking enzymatic activity.
