New cloning vectors were prepared with the aid of a large plasmid isolated from Acetobacter pasteurianus and from plasmids pBR322 and pUC4-KAPA. Of the prepared cloning vectors, pACK5 contains a gene coding for kanamycin resistance, pACT7 and pACT71 contain a gene coding for tetracycline resistance and vector pACG3 with a gene coding for both kanamycin and tetracycline resistance. The vectors prepared only contained the beginning of replication from the pAC1 plasmid and possessed the ability to replicate within E. coli and A. pasteurianus. The vectors are highly stable in both strains and during the 5-d cultivation under nonselective conditions are not eliminated.
借助从巴斯德醋酸杆菌中分离出的一种大质粒以及质粒pBR322和pUC4-KAPA制备了新的克隆载体。在所制备的克隆载体中,pACK5含有编码卡那霉素抗性的基因,pACT7和pACT71含有编码四环素抗性的基因,而载体pACG3含有编码卡那霉素和四环素抗性的基因。所制备的载体仅包含来自pAC1质粒的复制起始点,并具有在大肠杆菌和巴斯德醋酸杆菌中复制的能力。这些载体在两种菌株中都高度稳定,并且在非选择性条件下培养5天时不会被消除。
