基于规则的生化网络建模的动力学蒙特卡罗方法

Kinetic Monte Carlo Method for Rule-based Modeling of Biochemical Networks

Jin Yang, Michael I. Monine, James R. Faeder, William S. Hlavacek

摘要:

我们提出了一种动力学蒙特卡罗方法来模拟化学反应规则所指定的化学转化,这些规则可以被看作是化学反应的生成器,或者等价地,反应类的定义。一个规则确定了参与转化的分子成分,这些成分如何变化,影响转化是否发生的条件,以及速率定律。与传统的模拟方法不同,该方法的计算成本与可能反应的数量无关,不需要事先指定或在模拟中明确生成。为了证明该方法,我们应用它来研究多价配体-受体相互作用的动力学。我们希望这种方法将有助于研究细胞信号系统和其他物理系统涉及聚集现象。

英文摘要:

We present a kinetic Monte Carlo method for simulating chemical transformations specified by reaction rules, which can be viewed as generators of chemical reactions, or equivalently, definitions of reaction classes. A rule identifies the molecular components involved in a transformation, how these components change, conditions that affect whether a transformation occurs, and a rate law. The computational cost of the method, unlike conventional simulation approaches, is independent of the number of possible reactions, which need not be specified in advance or explicitly generated in a simulation. To demonstrate the method, we apply it to study the kinetics of multivalent ligand-receptor interactions. We expect the method will be useful for studying cellular signaling systems and other physical systems involving aggregation phenomena.
