An Algorithm for Initial Fluxes of Metabolic P Systems

Roberto Pagliarini, Giuditta Franco, Vincenzo Manca

Abstract


A central issue in systems biology is the study of efficient methods inferring fluxes of biological reactions by starting from experimental data. Among the different techniques proposed in the last years, the theory of Metabolic P systems, which is based on the Log-Gain principle, proved to be helpful for deducing biologi- cal fluxes from temporal series of observed dynamics. According to this approach, the algebraic systems provided by the Log-Gain principle determine the reaction fluxes underlying a system dynamics when initial fluxes are known. Here we propose a heuristic algorithm for estimating the initial fluxes, that is tested in two case studies.

Keywords


Biological modeling, P systems, MP systems, Metabolic flux esti- mation, Heuristic algorithms.
