The homology analysis showed that these 5 fragments had very high homologies with the maize mRNA that hade been separated . S_ had 80% homology with cytochrome b5 gene of N.tabacum . SCT-TG had over 90% homology with α-tublin gene of Z.mays , Eleusine indica, Hordeum vulgare, Oryza sativa and Setaria viridis.

序列同源性分析表明：这 5 条片段都与已经分离的玉米 mRNA 有很高的同源性，S_与烟草细胞色素 b5基因有 80%的同源性、SCT-TG与玉米、牛筋草、大麦、狗尾草、水稻等的α-微管蛋白基因有 90%以上的同源性。

Similar to the histological changes, the shape of the enzym lesion focus was also global, it contained a center showed no enzym activities and a low enzym activity peripheral zone of 5～7 cell layers well-demarcated from the normal activity tissues.

结果：1。射频消融能明显破坏心肌组织多种代谢酶的活性，使乳酸脱氢酶、琥珀酸脱氢酶、细胞色素氧化酶和钙ATP酶活性丧失或减低，而且各酶的损伤范围相同。

The 648 bp mitochondrial cytochrome c oxidase subunit I gene was examined in 8 species of raptors (5 species in Accipitridae, Falconiformes; 3 species in Strigidae, Strigiformes) by PCR with universal primers. 99 additional barcode sequences were downloaded to explore whether the DNA barcodes could distinguish between these species.

用DNA条形码通用引物扩增了我国8种猛禽（14只个体）的线粒体细胞色素c氧化酶亚基I基因，选取648 bp DNA条形码标准区域，结合99条猛禽条形码序列，探讨DNA条形码对猛禽的识别和鉴定。

And the IC50 values of all tested compounds did not change at various times. The panel of CYP3A4 polymorphic enzymes will be tested against various drugs, kinds of fluorogenic substrates and CYP3A4-specific substrate to identify potentially adverse drug-CYP in order to generate predictive information applicable in personalized medicine.

多种荧光底物、探针底物和大量的上市药物对人细胞色素P450 3A4野生株及其突变株的体外代谢研究正在进一步进行中，旨在建立一种高通量、简便、快捷的针对于CYP3A4遗传多态性的药物筛选平台，从而为临床个体化用药提供科学依据。

The divergence time between C.amherstiae and C.pictus was at least 1.7My based on the substitution rate of nucleotide acid of cytothrome-b gene in Galliformes.

根据鸡形目细胞色素b基因核苷酸替换的速率约为每百万年0.5％～ 0.7％，推断出两种锦鸡的分化时间至少为1.7百万年。

Objective To research the influences of gambogic acid on rats' cytochrome P450 isoforms by using the Cocktail probe drugs.

目的 用Cocktail探针药物法，研究藤黄酸对大鼠肝细胞色素P450(CYP450)的影响。

Methods Rats were randomly divided into several groups. One group of rats received gambogic acid solution containing 0.5% CMC-Na 2 mgmL^(-1, once per day orally for six days. At the same time, the rats in the other group received 0.5% CMC-Na solution serving as blank control group. Blood samples were collect at different time point, and the plasma concentration of cocktail probe drugs was determined by HPLC.

将SD大鼠随机分组，藤黄酸组给予藤黄酸0.5%CMC-Na溶液2mgmL^(-1，以0.5%CMC-Na为空白对照，在一定的时间点采集血样，通过HPLC检测探针药物在大鼠体内的代谢情况，以评价藤黄酸对肝细胞色素P450酶的影响。

Mutant libraries created by saturation mutagenesis of each single amino acid site D168, A225, K434 and E435 were screened to further improve the capability of cytochrome P450 BM-3(A74G/F87V/L188Q) mutant from Bacillus Megaterium which can hydroxylate indole into indigo. Results showed that D168, K434 and E435 are located at the functional domain of P450 BM-3 protein while A225 is sited at the unfunctional domain.

为了进一步获得具有更高活力的细胞色素P450 BM-3(F87V/A74G/L188Q)突变酶，利用饱和突变技术对该突变酶的4个氨基酸位点D168、A225、K434、E435分别进行单一的随机突变，通过对其羟基化吲哚生成靛蓝的催化性能表征，发现P450 BM-3氨基酸残基的168、434和435位均位于蛋白功能区域，而225位则位于非功能区域。
