本文介绍了用高能加速电子束研究细胞色素b_5还原酶的氧化还原反应机制。我们用高能加速电子束照射溶液时产生的水合电子束还原氧化态的细胞色素b_5还原酶,得到了既不是氧化态又不是还原态的新的吸收光谱,从而认为在该酶的氧化态和还原态之间还存在着中间态。 This article describes the use of high-energy accelerated electron beam cytochrome b_5 reductase redox reaction mechanism. We use high-energy accelerated electron beam irradiation solution generated hydrated electron beam reduction oxidation state of the cytochrome b_5 reductase, obtained neither a new absorption state nor a reduced absorption spectrum, which is considered in the enzyme oxidation state and reduction There is also a middle ground between states.
