In this work we aim to highlight a close analogy between cooperative behaviors in chemical kinetics and cybernetics; this is realized by using a common language for their description, that is mean-field statistical mechanics. First, we perform a one-to-one mapping between paradigmatic behaviors in chemical kinetics (i.e., non-cooperative, cooperative, ultra-sensitive, anti-cooperative) and in mean-field statistical mechanics (i.e., paramagnetic, high and low temperature ferromagnetic, anti-ferromagnetic). Interestingly, the statistical mechanics approach allows a unified, broad theory for all scenarios and, in particular, Michaelis-Menten, Hill and Adair equations are consistently recovered. This framework is then tested against experimental biological data with an overall excellent agreement. One step forward, we consistently read the whole mapping from a cybernetic perspective, highlighting deep structural analogies between the above-mentioned kinetics and fundamental bricks in electronics (i.e. operational amplifiers, flashes, flip-flops), so to build a clear bridge linking biochemical kinetics and cybernetics.
在这项工作中,我们旨在突出化学动力学与控制论中合作行为之间的紧密类比;这是通过使用一种共同语言来描述它们实现的,即平均场统计力学。首先,我们在化学动力学中的典型行为(即非合作、合作、超敏感、反合作)与平均场统计力学中的典型行为(即顺磁、高温和低温铁磁、反铁磁)之间进行一一映射。有趣的是,统计力学方法为所有情况提供了一个统一的、广泛的理论,特别是,米氏方程、希尔方程和阿代尔方程能够一致地推导出来。然后,这个框架与实验生物学数据进行了测试,总体上具有极好的一致性。更进一步,我们从控制论的角度连贯地解读整个映射,突出上述动力学与电子学中的基本元件(即运算放大器、闪光灯、触发器)之间深刻的结构类比,从而搭建起一座连接生化动力学与控制论的清晰桥梁。
