A stochastic model of Min oscillations in Escherichia coli and Min protein segregation during cell division.
The Min system in Escherichia coli directs division to the centre of the cell through pole-to-pole oscillations of the MinCDE proteins. We present a one-dimensional stochastic model of these oscillations which incorporates membrane polymerization of MinD into linear chains. This model reproduces much of the observed phenomenology of the Min system, including pole-to-pole oscillations of the Min...
متن کاملDivision accuracy in a stochastic model of Min oscillations in Escherichia coli.
Accurate cell division in Escherichia coli requires the Min proteins MinC, MinD, and MinE as well as the presence of nucleoids. MinD and MinE exhibit spatial oscillations, moving from pole to pole of the bacterium, resulting in an average MinD concentration that is low at the center of the cell and high at the poles. This concentration minimum is thought to signal the site of cell division. Det...
متن کاملMin-protein oscillations in round bacteria.
In rod-shaped Escherichia coli cells, the Min proteins, which are involved in division-site selection, oscillate from pole-to-pole. The homologs of the Min proteins from the round bacterium Neisseria gonorrhoeae also form a spatial oscillator when expressed in wild-type and round, rodA- mutants of E. coli, suggesting that the Min proteins form an oscillator in N. gonorrhoeae. Here we report tha...
متن کاملStuttering Min oscillations within E. coli bacteria: a stochastic polymerization model.
We have developed a 3D off-lattice stochastic polymerization model to study the subcellular oscillation of Min proteins in the bacteria Escherichia coli, and used it to investigate the experimental phenomenon of Min oscillation stuttering. Stuttering was affected by the rate of immediate rebinding of MinE released from depolymerizing filament tips (processivity), protection of depolymerizing fi...
متن کاملA Hybrid Min-min Max-min Algorithm with Improved Performance
The high cost of supercomputers and the need for large-scale computational resources has led to the development of network of computational resources known as Grid. To better use tremendous capabilities of this large scale distributed system, effective and efficient scheduling algorithms are needed. Many such algorithms have been designed and implemented. We introduce a new scheduling algorithm...
