Abstract

The electron transfer reactions between Rhus vernicifera stellacyanin and either horse heart cytochrome c or Pseudomonas aeruginosa cytochrome c551 were investigated by rapid reaction techniques. The time course of electron transfer is monophasic under all conditions, and thus consistent with a simple formulation of the reaction. Both stopped-flow and temperature-jump experiments yield equilibrium constants in reasonable agreement with values calculated from the redox potentials. The differences in reaction rate between the two cytochromes and stellacyanin are discussed in terms of the Marcus theory.

摘要

利用快速反应技术研究了漆树紫铜蓝蛋白与马心细胞色素c或铜绿假单胞菌细胞色素c551之间的电子转移反应。在所有条件下，电子转移的时间进程都是单相的，因此与该反应的简单公式一致。停流实验和温度跃升实验得到的平衡常数与根据氧化还原电位计算的值相当吻合。根据马库斯理论讨论了两种细胞色素与紫铜蓝蛋白之间反应速率的差异。
