Abstract
The potentials of the couples Mo(IV)--(Mo(V) and Mo(V)--Mo(VI) in nitrate reductase from Escherichia coli K12 were measured as + 180 mV and + 220 mV respectively at pH 7.14. The potentials associated with two other e.p.r. signals, believed to be due to iron--sulphur centres, were measured as + 50 mV and + 80 mV.
摘要
在pH 7.14条件下，对来自大肠杆菌K12的硝酸还原酶中Mo(IV)–(Mo(V)和Mo(V)–Mo(VI)这两对的电位进行了测量，结果分别为 +180毫伏和 +220毫伏。与另外两个据信由铁硫中心引起的电子顺磁共振信号相关的电位经测量为 +50毫伏和 +80毫伏。
