title: Synthesis of mRNA of malB operons at specific stages in the cell cycle of Escherichia coli.
abstract: 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.
