By using of the Tripos sybyl software, three-dimensional(3D) model of p450nor2 was established based on high sequence similarity to homologous protein p450nor1 structure and the perfect homology modeling was obtained.

基于细胞色素P450nor2与同源蛋白P450nor1氨基酸序列的相似性，采用Tripos sybyl软件对细胞色素P450nor2进行同源模建和分子叠合，获得了理想的同源模建结果。

Mitochondrial cytochrome b gene were sequenced in 44 geese of Chinese domestic geese(15 breeds) and European domestic geese(2 breeds). Anatidae molecular clocks was calibrated with 2 consensus sequences which come from Chinese domestic geese and European domestic geese and 13 sequences obtained from GenBank.

本实验测定了中国家鹅15个品种、欧洲鹅2个品种共44个个体的细胞色素b基因全序列，分别取鸿雁和灰雁家鹅的一致序列与GenBank库中的13条鸟类(鸡形目4条、鸭科鸟类9条)细胞色素b基因部分序列(1045bp)共15条序列构成本研究的数据集。

The bacterial, mammalian and plant cytochrome P450s involved in metabolism of herbicides are reviewed in this paper. The action modes of cytochrome P450s on herbicides including dealkylation, ring-methyl hydroxylation and aromatic ring hydroxylation etc are summarized.

本文综述了代谢除草剂的细菌、哺乳动物和植物细胞色素P450酶系，概述了细胞色素P450酶系参与除草剂代谢的作用方式：脱烷基化作用、环甲基化羟基化作用和芳环的羟基化作用等。

PartⅢEffect of DM on release of cytochrome C in neurocyte mitochondria Objectivity: To study the effect of DM on release of cytochrome C in neurocyte mitochondria.

第三部分溴氰菊酯对神经细胞线粒体细胞色素C释放的影响目的：探讨溴氰菊酯对神经细胞线粒体细胞色素C释放的影响。

RESULTS: HIF-1α positively expressed at stratum neuroepitheliale retinae and purpurogenous membrane in the embryonic phase. Additionally, HIF-1α still positively expressed at stratum neuroepitheliale retinae and purpurogenous membrane, especially in ganglionic cells and inner plexiform layer, in early development.

结果：胚胎期视网膜神经上皮层及色素上皮层均有低氧诱导因子1α阳性表达，生后发育早期视网膜神经上皮层及色素上皮层也可见低氧诱导因子1α阳性表达，以神经节细胞、内网层更明显，随着发育进展，其阳性表达主要位于视网膜节细胞层。

Long period illumination could lower the activity of cytochrome oxidase in tissues, so that this enzyme activity in green leaves was much lower than that in etiolated leaves. The activity of isolated cytochrome oxidase, however, was not affected with light of varied intensities.

虽然光的长期作用能降低细胞色素氧化酶活性，使绿叶中该酶的活性大大低于黄化苗，但各种强度的光对提取的细胞色素氧化酶活性没有影响。

Measurement of cytochrome oxidase activity in germinated seeds, etiolated leaves and green leaves of pea indicated that the cytochrome oxidase activity was correlative to the importance of energy generation in the process of mitochondrial coupling respiration.

豌豆萌发种子、黄化苗和绿叶的细胞色素氧化酶活性测定表明，细胞色素氧化酶活性在黄化苗、萌发种子、绿叶中依次递减，与线粒体偶联呼吸产生能量在该组织中的重要性呈正相关。

The surface hydrophobicity of chicken heart apocytochrome c with different unfolded states has been compared by hydrophobic chromatography and by assessing their ability to bind a hydrophobic probe, 1,8-ANS.

鸡心脱血红素细胞色素c具有较强的自发折叠的能力，在一定条件下可以得到不同解折叠状态的鸡心脱血红素细胞色素c。

The wild type protein and mutant S103A was shown to exhibit the same folding tendency as that chemically prepared from chicken heart cytochrome c, while mutants containin the V92A mutation not any more.

表达纯化的、野生型的鸡脱血红素细胞色素c具有从鸡心细胞色素c化学制备的蛋白相同的折叠性质。

Chicken heart apocytochrome c has much stronger tendency to fold spontaneously than those from other species. The partial folding also influences its interaction with phospholipid, and greatly decreased its translocation efficiency on the model membrane system.

鸡心脱血红素细胞色素c具有较其它种类脱血红素细胞色素c较强的自发折叠倾向性，其部分折叠也影响与脂的相互作用，大大降低其在模型膜上的转运效率。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
