在甲基紫精存在下，使用金电极研究了铁氧还蛋白的氧化还原性质。氧化还原电位值为-0.42.+-。 0.01V/n.h.e. [标准氢电极]已确认为C. pateurianum ferredoxin。对于热稳定性 C.thermocellum 铁氧还蛋白，氧化还原电位值为 -0.43.+-。 0.01V/n.h.e.获得。电化学活化归因于金电极表面吸附的甲基紫精的存在。
The redox properties of ferredoxins were studied using the gold electrode in the presence of methyl viologen. A redox potential value of -0.42 .+-. 0.01 V/n.h.e. [normal hydrogen electrode] is confirmed for C. pateurianum ferredoxin. For the thermostable C. thermocellum ferredoxin, a redox potential value of -0.43 .+-. 0.01 V/n.h.e. is obtained. The electrochemical activation is attributed to the presence of methyl viologen adsorbed onto the gold electrode surface.
