title: Optimization of error-correction processes with respect to time. Comparison to free energy aspects.
abstract: Time aspects of selection processes with the possibility of error correction through proofreading branches are studied by mathematical modelling of the kinetics of the reaction network. The methods are similar to those previously developed for free energy aspects. The minimum time delay that is necessary for achieving a certain accuracy level can then be calculated. The main difference to previous results lies in the initial association-dissociation step. In the free energy picture, this shall be essentially equilibrated, but that would yield a too large time delay in the time picture. Characteristic features that are indicative for the optimization strategy of the cell are discussed.
