代谢网络中的活性通量分布

Viable flux distribution in metabolic networks

Ginestra Bianconi, Riccardo Zecchina

摘要:

代谢网络在大规模生物网络中是一个独特的案例,它在大量生物中得到了很好的表征。出于这个原因,他们提供了一个非常有趣的框架,分析听话的统计力学模型的建设。在本文中,我们介绍了一个可解模型的流量分布的代谢网络。我们表明,通量的分布上的拓扑结构的效果是允许其值的大的波动,这一事实应该有影响系统的鲁棒性。

英文摘要:

The metabolic networks are very well characterized for a large set of organisms, a unique case in within the large-scale biological networks. For this reason they provide a a very interesting framework for the construction of analytically tractable statistical mechanics models. In this paper we introduce a solvable model for the distribution of fluxes in the metabolic network. We show that the effect of the topology on the distribution of fluxes is to allow for large fluctuations of their values, a fact that should have implications on the robustness of the system.
