Abstract

The kinetic model of Ragan & Cottingham [(1985) Biochim. Biophys. Acta 811, 13-31] for electron transport through a mobile pool of quinone predicts that, under certain conditions, the normal linear dependence of electron flow on the degree of reduction (or oxidation) of the quinone should no longer be found. These conditions can be met by reconstituted NADH: cytochrome c reductase (Complex I-III from bovine heart) when electron flow is rate-limited by a low concentration of cytochrome c. We show that, in such a system, the dependence of activity (varied by inhibition with rotenone) on the steady-state level of quinone reduction is indeed non-linear and very closely accounted for by the theory.

摘要

拉根和科廷厄姆[（1985年）《生物化学与生物物理学报》811卷，第13 - 31页]提出的关于电子通过醌的流动池进行传输的动力学模型预测，在某些条件下，电子流对醌的还原（或氧化）程度的正常线性依赖关系将不再存在。当电子流受低浓度细胞色素c的速率限制时，重组的NADH：细胞色素c还原酶（来自牛心的复合体I - III）可以满足这些条件。我们表明，在这样一个系统中，活性（通过鱼藤酮抑制来改变）对醌还原稳态水平的依赖性确实是非线性的，并且该理论能非常精确地解释这一现象。
