A simulation model of prokaryotic Z-ring assembly, based on the observed behavior of FtsZin vitroas well as onin vivoparameters, is used to integrate critical processes in cell division. According to the model, the cell’s ability to divide depends on a “contraction parameter” (χ) that links the force of contraction to the dynamics of FtsZ. This parameter accurately predicts the outcome of division. Evaluating the GTP binding strength, the FtsZ polymerization rate, and the intrinsic GTP hydrolysis/dissociation activity, we find that inhibition of GTP–FtsZ binding is an inefficient antibacterial target. Furthermore, simulations indicate that the temperature sensitivity of theftsZ84mutation arises from the conversion of FtsZ to a dual-specificity NTPase. Finally, the sensitivity to temperature of the rate of ATP hydrolysis, over the critical temperature range, leads us to conclude that theftsZ84mutation affects the turnover rate of the Z-ring much less strongly than previously reported.
