Objective : We investigated the relationship between Ada protein and the effective transcription of alkA gene in order to study the regulation of alkA gene expression by Ada protein .

目的：研究Ada蛋白质对alkA基因表达的调节，探讨Ada蛋白质与alkA基因有效转录的关系。

Results : The amount of alkA mRNA transcripted from mutant and wild alkA gene promoters was higher in the group in presence of Ada protein than that in the group without Ada protein .

结果：Ada蛋白质加入以突变和野生alkA基因启动子为模板的体外转录体系中，产生的alkAmRNA高于无Ada蛋白质组；
