The standard redox potentials of soluble cytochromes c isolated from the green alga Chlorella and the blue-green algae Spirulina and Aphanezomenon were determined by potentiometric titration and found to be equal to +380 mB, +330 mB and +357 AB, respectively. The standard redox potentials of plastocyanin preparations from Pisum sativum and Atriplex leaves were also determined and found close to those of soluble cytochromes c, i. e. +395 mB and +375 mB, respectively. The metalloproteins studied were shown to belong to monoelectron carriers operating at the donor sites of photosystem I.
通过电位滴定法测定了从绿藻小球藻、蓝藻螺旋藻和钝顶螺旋藻中分离出的可溶性细胞色素c的标准氧化还原电位，结果发现分别为+380毫伏、+330毫伏和+357毫伏。还测定了来自豌豆和滨藜叶的质体蓝素制剂的标准氧化还原电位，发现其接近可溶性细胞色素c的电位，即分别为+395毫伏和+375毫伏。所研究的金属蛋白被证明属于在光系统I供体部位起作用的单电子载体。
