Abstract Background Many computer studies have employed either dynamic simulation or metabolic flux analysis MFA to predict the behaviour of biochemical pathways. Dynamic simulation determines the time evolution of pathway properties in response to environmental changes whereas MFA provides only a snapshot of pathway properties within a particular set of environmental conditions. However owing to the large amount of kinetic data required for dynamic simulation MFA which requires less information has been used to manipulate large-scale pathways to determine metabolic outcomes. Results Here we describe a simulation method based on cooperation between kinetics-based dynamic models and MFA-based static models. This hybrid method enables quasi-dynamic simulations of large-scale metabolic pathways while drastically reducing the number of kinetics assays needed for dynamic simulations. The dynamic behaviour of metabolic pathways predicted by our .
