The electrons are transferred along the chain to a carrier molecule ( coenzyme q ) , and then in sequence to a series of cytochromes , finally acting with the enzyme cytochrome oxidase to reduce an oxygen atom , which combines with two h + ions to form water 电子沿呼吸链传递到载体分子? ?辅酶q上，然后依次经过一系列细胞色素分子的传递，最后与细胞色素氧化酶反应，氧原子结合两个氢形成水从而被还原。
In this optimal condition , p450nor was expressed massively . the expressed product was then purified by deae - cellulose chromatography . the purified expressed protein showed one band in sds - page and the purification attained anticipative purpose 在此条件下，大规模诱导表达重组细胞色素p450nor ，经deae纤维素色谱柱纯化， sds - page分析表明，纯化的目的蛋白基本上为单一谱带，纯化达到预期效果。
The effects of sfamnpv on apoptosis - related protein bcl - 2 and cyto c were investigated by western blotting . sfamnpv could down - regulate the level of bcl - 2 expression after induction for 8h . also , cyto c was released from mitochondrial to cytosolic after induction for 4h 杂交可看到sl - 1细胞在接种病毒的4h后线粒体中的细胞色素c被释放到了细胞质中，这与很多在哺乳动物细胞中所作的结果是相同的。
The recombinant expression plasmids prt - p450nor and pet - p450nor were constructed by inserting p450nor gene into the bamh i / hind iii site of the prokaryotic expression vector prset and pet28 , then they were transformed into e . coli bl21 本研究将已克隆的真菌细胞色素p450nor基因插入原核表达质粒载体prset和pet28的bamhi / hind位点，成功构建重组表达质粒prt - p450nor和pet - p450nor ，并转化到e . colibl21 。
New york ( reuters health ) dec 19 - carriers of a polymorphism of the cytochrome p450 enzyme are at higher risk of miscarriage in the first trimester of pregnancy , karolinska university investigators report in the november issue of fertility and sterility 纽约（路透社健康版） 12月19日? ?卡罗琳斯卡大学的研究者在11月号的《生育与不育》上撰文指出，细胞色素p450酶多态性携带者妊娠早期流产的风险要大一些。
During dark adaptation , the rhabdomal figures are regular , the distal pigment granules and proximal pigment granules are concentrated in the distal of crystalline tract and the proximal rhabdom respectively , and while retinular pigment granules are lacked in proximal of ommatidium 暗适应时，感杆束外形规则，微绒毛排列整齐，远端色素则集中于小眼的远端，近端缺乏小网膜细胞色素，仅有近端反光色素分布。
A world - renowned scientist in the field of biophysical chemistry , prof . chan is particularly well - known for his seminal contribution to the understanding of the structures and functions of several important membrane proteins such as cytochrocome c oxidase , for which he was nominated for a nobel prize 这位名闻遐迩的科学家在研究如细胞色素氧化?等多种重要膜蛋白质的结构及功能上有深远的贡献，曾获提名角逐诺贝尔奖。
In order to develop an accurate and efficient method for the identification of tiger dna , mtdna ctyb sequences of 5 tiger subspecies and 6 other feline species and 6 cervid species were downloaded from genbank , and compared by wdnasis ( v2 . 5 ) software 为了建立对虎dna进行特异性检测的有效、精确的方法，本研究中，从genbank下载虎及其他6种猫科动物和6种鹿科动物的mtdna细胞色素b基因序列，并用wdnasis ( v2 . 5 )软件进行了种间序列比较。
Toxicology : glutathione is a key substrate for the cytochrome p450 metabolic pathway , which is taxed daily , not only by a variety of prescription and non - prescription drugs , but also by a host of environmental toxins including heavy metals and many by - products of cigarette smoke and fuel exhaust 毒理学：谷胱甘肽是细胞色素p450代谢途径的关键基质，每天都被除了各种的处方和非处方药品外还有包括重金属、抽烟副产物及排气等许多的环境毒物所消耗。
Cytochrome p450 functions as the monooxygenase . p450s are involved in physiologically important processes including steroid metabolism , drug deactivation , procarcinogen activation , fatty acid metabolism , xenobiotic detoxification and wildly distributed in animal , plant and low eukaryotic organism 细胞色素p450具有加单氧酶的作用，并能参与机体解毒、甾体激素的合成、脂肪酸代谢等重要的生理反应，并广泛分布于动物、植物和低等真核生物中。
