代谢网络的灵敏度:干扰代谢物浓度

Sensitivity of metabolic networks: perturbing metabolite concentrations

Nicola Vassena

摘要:

灵敏度研究网络对扰动的响应。我们考虑局部扰动的浓度的代谢物在平衡。我们调查的网络中的反应,代谢物的浓度和反应通量。我们的方法纯粹是定性的,而不是定量的。事实上,我们的分析仅仅基于反应网络的化学计量,我们不需要任何关于反应速率的定量信息。相反,这种描述仅用代数术语进行,所需的唯一数据是网络结构。生物学应用包括代谢控制和网络重建。

英文摘要:

Sensitivity studies the network response to perturbations. We consider local perturbations of the concentrations of metabolites at an equilibrium. We investigate the responses in the network, both of the metabolite concentrations and of the reaction fluxes. Our approach is purely qualitative, rather than quantitative. In fact, our analysis is based, solely, on the stoichiometry of the reaction network and we do not require any quantitative information on the reaction rates. Instead, the description is done only in algebraic terms, and the only data required is the network structure. Biological applications include metabolic control and network reconstruction.
