Genetic analysis of the cell cycle of Caulobacter crescentus has identified a DNA synthetic pathway and a cell division pathway (M. A. Osley and A. Newton, J. Mol. Biol. 138:109-128, 1980). The results presented here show that in double-shift experiments the function of the PC2076 gene product, which is required for the initiation of DNA synthesis, depends on completion of a late stage of chromosome replication in the previous cell cycle. These findings suggest a circular organization of steps in the DNA synthetic pathway in C. crescentus.
新月柄杆菌细胞周期的遗传分析确定了一条DNA合成途径和一条细胞分裂途径(M. A. 奥斯利和A. 牛顿,《分子生物学杂志》138:109 - 128,1980年)。本文给出的结果表明,在双转移实验中,DNA合成起始所需的PC2076基因产物的功能取决于前一个细胞周期中染色体复制后期的完成。这些发现提示了新月柄杆菌DNA合成途径中各步骤的环状组织形式。
