E.p.r. spectra of reduced iron-sulphur centres of the aldehyde oxidoreductase (iron-molybdenum protein) of Desulfovibrio gigas were recorded at X-band and Q-band frequencies and simulated. Results are consistent with the view that only two types of [2Fe-2S] clusters are present, as in eukaryotic molybdenum-containing hydroxylases. The data indicate the Fe/SI centre to be very similar, and the Fe/SII centre somewhat similar, to these centres in the eukaryotic enzymes.
在X波段和Q波段频率下记录并模拟了巨大脱硫弧菌醛氧化还原酶(铁钼蛋白)的还原态铁硫中心的电子顺磁共振(E.p.r.)光谱。结果与如下观点一致:与真核含钼羟化酶一样,仅存在两种类型的[2Fe-2S]簇。数据表明,Fe/SI中心与真核酶中的这些中心非常相似,Fe/SII中心与真核酶中的这些中心有些相似。
