Interrogating the Escherichia coli cell cycle by cell dimension perturbations.
Bacteria tightly regulate and coordinate the various events in their cell cycles to duplicate themselves accurately and to control their cell sizes. Growth of Escherichia coli, in particular, follows a relation known as Schaechter's growth law. This law says that the average cell volume scales exponentially with growth rate, with a scaling exponent equal to the time from initiation of a round o...
متن کاملGalactose-Binding Protein by the Cell Cycle of Escherichia coli
The synthesis of the periplasmic galactose-binding protein of E. coli is regulated by events occurring during its cell cycle, and proceeds in synchronized cells for only a short period after cell division is completed. Transport activity mediated by the fl-methylgalactoside transport system follows closely the synthesis pattern of the binding protein. A mutant, E. coli BUG-6, exhibits temperatu...
متن کاملLipid synthesis during the Escherichia coli cell cycle.
Lipid synthesis was examined in Escherichia coli cells at different stage of cell division. Exponentially growing cells were pulse-labeled with appropriate isotopes for 0.1 generation time, inactivated, and separated by size on a sucrose gradient. An abrupt increase in the rate of lipid synthesis occurred which was coincident with the initiation of cross walls. In contrast, the rate of protein ...
متن کاملAspC-Mediated Aspartate Metabolism Coordinates the Escherichia coli Cell Cycle
BACKGROUND The fast-growing bacterial cell cycle consists of at least two independent cycles of chromosome replication and cell division. To ensure proper cell cycles and viability, chromosome replication and cell division must be coordinated. It has been suggested that metabolism could affect the Escherichia coli cell cycle, but the idea is still lacking solid evidences. METHODOLOGY/PRINCIPL...
متن کاملProtein turnover in the cell cycle of Escherichia coli.
Nishi, Arasuke (University of Tokyo, Tokyo, Japan), and Tokio Kogoma. Protein turnover in the cell cycle of Escherichia coli. J. Bacteriol. 90:884-890. 1965.-Protein metabolism and enzyme formation throughout the cell cycle were investigated in synchronized cultures of Escherichia coli. The cells showed a temporary cessation of the net increase of bulk protein and of constitutive beta-galactosi...
