The mRNA synthesis of the malB operons was examined using synchronous cultures of Escherichia coli. mRNA of the malB operons were synthetized in cell cycle-specific manners different from the bulk mRNA synthesis. The synthesis occurred in two stages during a cell cycle, one in the middle of the cycle and the other at the time slightly before cell division. Identification of the species of mRNA revealed that the malK-lamB operon was preferably transcribed in the former stage of the cycle while a major fraction of mRNA of the malE-malF operon was synthesized in the later stage.
利用大肠杆菌的同步培养物检测了malB操纵子的mRNA合成。malB操纵子的mRNA以不同于整体mRNA合成的细胞周期特异性方式进行合成。这种合成在细胞周期的两个阶段发生，一个在周期中期，另一个在细胞分裂前稍早的时候。mRNA种类的鉴定表明，malK-lamB操纵子在周期的前一阶段优先转录，而malE-malF操纵子的大部分mRNA在后期合成。
