Clocking out: modeling phage-induced lysis of Escherichia coli
Ryan, G. L., and A. D. Rutenberg. 2007. "Clocking out: modeling phage-induced lysis of Escherichia coli." Journal of Bacteriology 189(13): 4749-4755.Phage lambda lyses the host Escherichia coli at a precisely scheduled time after induction. Lysis timing is determined by the action of phage holins, which are small proteins that induce hole formation in the bacterium's ... -
Maximally fast coarsening algorithms
Cheng, M., and A. D. Rutenberg. 2005. "Maximally fast coarsening algorithms." Physical review.E, Statistical, nonlinear, and soft matter physics 72(5 Pt 2): 055701.We present maximally fast numerical algorithms for conserved coarsening systems that are stable and accurate with a growing natural time step Deltat=At2/3s. We compare the scaling structure obtained from our maximally fast ... -
Pulling helices inside bacteria: imperfect helices and rings
Allard, J. F., and A. D. Rutenberg. 2009. "Pulling helices inside bacteria: imperfect helices and rings." Physical Review Letters 102(15): 158105.We study steady-state configurations of intrinsically-straight elastic filaments constrained within rod-shaped bacteria that have applied forces distributed along their length. Perfect steady-state helices result from axial ... -
Self-organization of the MinE protein ring in subcellular Min oscillations
Derr, J., J. T. Hopper, A. Sain, and A. D. Rutenberg. 2009. "Self-organization of the MinE protein ring in subcellular Min oscillations." Physical review.E, Statistical, nonlinear, and soft matter physics 80(1 Pt 1): 011922.We model the self-organization of the MinE ring that is observed during subcellular oscillations of the proteins MinD and MinE within the rod-shaped bacterium Escherichia coli. With a steady-state approximation, we can ... -
Steady-state helices of the actin homolog MreB inside bacteria: dynamics without motors
Allard, J. F., and A. D. Rutenberg. 2007. "Steady-state helices of the actin homolog MreB inside bacteria: dynamics without motors." Physical review.E, Statistical, nonlinear, and soft matter physics 76(3 Pt 1): 031916.Within individual bacteria, we combine force-dependent polymerization dynamics of individual MreB protofilaments with an elastic model of protofilament bundles buckled into helical configurations. We use variational ... -
Unwinding scaling violations in phase ordering
