The structure of the Rho GTP-binding proteins network given in [] and the dominant fluxes obtained by stochastic flux analysis on this network. Left: The arrows denote the reactions of the network. R denotes the Rho GTP-binding protein, whereas RD and RT denote its GDP and GTP bound forms. A and E denote GAP and GEF. Thus, RDE, for example, denotes the protein complex formed by RD and E. The thick arrows denote the dominant fluxes obtained by the analysis in . Right: The dominant fluxes obtained by stochastic flux analysis include the fluxes marked with ∗ and excludes the ones marked with # on the left. This analysis indicates also the fluxes due to the enzymes A and E.
