The results are as follows: the DDM detergent dissolves the Cyt b6f better thanβ-OG detergent does; DDM can keep the Cyt b6f in native state, under which the hemes and Chl a experience specific environment, while theβ-OG make the complex in denatured state in some sort, under which the catalyzed electron transfer activity of the complex

结果表明，DDM去垢剂能使Cyt b6f处于较好的分散体系中，其中血红素和Chl a分子处于特定的蛋白环境中，不会导致Cyt b6f变性；而β-OG去垢剂会使Cyt b6f产生聚合现象，其中的血红素和Chl a与蛋白环境的相互作用减弱，和DDM相比其电子传递活性显著降低，Chl a单线激发态寿命延长，Chl a更容易被光

In addition to the two axial ligations provided by His18 and Met80, the hydrogen bond and hydrophobic interactions between the heme and the protein polypeptide, the heme also covalently linked to the protein matrix through two thioether bonds which are formed between vinyl groups of the heme and cysteine residues of a classic Cys-Xaa-Xaa-Cys-His heme-binding motif of the polypeptide chain.

Cyt c是血红素蛋白中电子传递蛋白的典型代表，其辅基heme与蛋白肽链的结合除了来自heme轴向配体组氨酸(His18)和甲硫氨酸(Met80)的配位作用、氢键和疏水相互作用等非共价键作用方式外，血红辅基heme的两个乙烯基还与蛋白肽链上的结构片段域Cys-Xaa-Xaa-Cys-His中的两个半胱氨酸形成硫醚键以共价键方式相结合。

PSⅡmaximum efficiency, quantum efficiency of PSⅡ,PSⅡoperating efficiency and electron transfer rate of leaf in the light-adapted were increased withyear of release.

髓品种育成年代增加，剑叶光适应条件下的Fv′／Fm′、Φ_、qP和ETR增加，即PSⅡ的激发能捕获效率、光化学量子效率度、反应中心的开放程和电子传递速率都增加。

The electron transfer kinetics of n-alkanethiol monolayers on Au(111) electrode is investigated.

使用电化学方法研究了Au(111)电极上的烷基硫醇分子自组装膜的电子传递动力学。

The comparison with the previously determined homologous complex from Escherichia coli reveals structural divergence in the surroundings of the prosthetic groups and in the membrane embedded domain, especially in respect to the proposed ubiquinone binding sites.

通过与之前解析的源于大肠杆菌的同源结构比较，本研究揭示了复合物内电子传递体周围结构环境的差别，特别是关于推测的醌结合位点的差别。

The OXPHOS electron transfer chain (mitochondrial respiration chain) is located on the inner membrane of mitochondrion and comprising of four large trans-membrane protein complexes (mitochondrial respiratory Complex I, II, III and IV) as well as ubiquinone between Complex I/II and III and cytochrome c between Complex III and IV.

摘 要：线粒体作为真核细胞的重要&能量工厂&，是细胞进行呼吸作用的场所，呼吸作用包括柠檬酸循环和氧化磷酸化两个过程，其中氧化磷酸化过程的电子传递链位于线粒体内膜上，由四个相对分子质量很大的跨膜蛋白复合体(I、II、III、和IV)、介于I/II 与III之间的泛醌以及介于III 与IV之间的细胞色素c共同组成。

Copper-containing nitrite reductases ; Electron transfer ; Catalytic mechanism ; Denitrification

铜型亚硝酸还原酶；电子传递；催化机理；生物脱氮

Oxygen evolution , thermoluminescence , polyphasic rise of fluorescence transients and Western-blotting were measured, in order to study the effects of

结果显示：随盐浓度的增加，螺旋藻细胞光合放氧活性和PS II电子传递活性下降；TL B-band和Q-band强度降低，在0-0.6M NaCl下，B-band的周期性振荡清楚，最大值出现在第二次和第六次闪光，而在0.8M NaCl时，S态振荡基本上消失，S态氧化还原循环受阻；Fm， J、I和P相荧光水平降低。

I am sure after a few weeks of adaptation and familiarization I will have no difficulty in functioning on a daily basis in an English speaking society or in participating fully in graduate studies.
