This paper discussed the metabolic pathway of soya iso - flavone in human body . the pharmacology function of soya iso - flavone was also reviewed in anti - cancer , inhibiting osteoporosis , alternating therapy of female hormone , and preventing cardiovascular diseases 论述了大豆异黄酮在人体中的代谢途径及其抗癌,抑制骨质疏松,雌激素替代治疗,防治心血管疾病的作用与药理,为异黄酮的开发利用及在其他豆科作物中的应用提供借鉴。
Analysis of activity of p - galactosidase showed that cryld - lacz expressed differently in the same host because of different carbon sources and differenly in different hosts utlizing same carbon sources , suggesting that metabolism pathway of carbon source in hd - 133 - 5 was special 首次报道了cry1d - lacz在同一菌株中的表达因碳源不同而异,在碳源相同的条件下不同菌株的表达也不相同,而衍生菌株hd - 133 - 5的代谢途径非常特殊。
Phytoene desaturase ( pds ) has recently been identified as an important enzyme in carotenoid metabolitic pathway . a new full - length cdna clone encoding phytoene desaturase gene was isolated from stigma of saffron using rt - pcr and race techniques ( ( genbank accession no . ay 183118 ) ) 其中主要的活性成分是西红花甙,需经类胡萝卜素代谢途径合成,而八氢番茄红素脱氢酶( phytoenedesaturase )是此途径中的一个早期关键酶。
The seed - specific promoter commonly under investigation today belongs to promoter , which can promote the exogenous genes to express specifically in the seed , improve the plant metabolism path as desired , and raise the nourishment material content in the seed 目前州门所广泛研究的种子特异性启动子基本上属于类启动子,它可以驱使外源基因在植物的种子中特异表达,按照人们的意愿改进植物代谢途径,提高种子中营养物质含量等。
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。
4 . engineering dhqase ( arod ) - deficient e . coli mutant with a second copy of the arob gene gene targeting technique was used to disrupt the arod gene in e . coli chromosome . the mutant 31bk was engineered , in which homologous recombination of the arobkanr gene cassette into the arod locus ( arod : : arobkanr ) of the e . coli strain atcc31884 genome utilized the helper plasmid pkd46 with red system . the host cell 31bk lacked catalytic activity of dhqase ( arod ) and had a second copy of the arob gene , so it improved carbon flow into the quinic acid biosynthesis direction 构建宿主菌基因精确定位突变株31bk ( arod : : arobkan ~ r )为了改变代谢途径脱氢奎尼酸( dhq )分支点上的代谢流量,使之充分流向目的产物奎尼酸合成方向,利用基因打靶技术构建了31884宿主菌arod基因精确定位插入突变体,使dhq脱水酶( dhqase )失活,阻断了碳代谢流流向芳香氨基酸生成的方向,同时用同源重组的方法将arob基因定位整合入染色体上,解除了限速酶对碳代谢流通过共同途径到达dhq的阻遏影响,并减轻代谢负担。
From the result of electrophoresis , it known that the different components of the enzyme system were expressed cooperatively . in order to study the essence of cellualase induction of different carbon sources , the extracellular , plasm - membrane - bound and intracellular cellulases were made to transform different soluble inducers , and the productions were analyzed by gc chromatogram . the results supported the assumption that cellobiose acted as the direct inducer or the metabolic analogue , b - gentiobiose from cellobiose acted as the true inducer through different metabolism ways in different strains 制备细胞膜外、细胞膜、细胞内纤维素酶,用定位于这三部位的纤维素酶分别转化底物,然后进行气相色谱定性分析,从而探讨了不同碳源之间的诱导本质,结果认为不可溶的胞外纤维素以纤维二糖为桥梁,遵循不同的代谢途径,直接或间接地诱导了两株不同真菌纤维素酶的合成。
About 25 salt - induced proteins were identified by maldi - tof / ms , and finally the function of 17 induced proteins were determined , including heat - shock proteins ( groes , clp ) . abc transporter , rna polymerase ( p - subunit ) and enzymes involved in signal transduction and metabolism . meanwhile , 84 proteins were idifferentially expressed after salt shock 5 min and 50 min in late exponential phase 应用maldi - tof ms对30个盐胁迫蛋白进行分析,已初步确定17个诱导蛋白的功能,其中包括与盐胁迫相关的热激蛋白( groes 、 clp ) 、与代谢途径和信号传导等有关的酶,以及abc转运蛋白、转录调节蛋白、 rna聚合酶的亚基等。
Abc transporter , the elongation factors ( ef - tu ) and the other enzymes involved electron transduction and metabolism . finally , comparing long - termed salt stress with transient salt shock , there are 12 proteins induced in common , which means different stress regulatory mechanisms are inextricably linked to each other 应用maldi - tof ms分析,已初步确定25个诱导蛋白的功能,其中包括亲和溶质脯氨酸合成必需的酶、 abc转运蛋白、热激蛋白( hsp60 ) 、 dnak及蛋白合成的伸长因子ef - tu 、与代谢途径、信号传导和电子传递系统有关的酶。
The global regulator csra of e . coli is a specific mrna - binding protein . csra negatively regulates several metabolic pathways that are induced post - exponentially , including glycogen biosynthesis , gluconeogenesis , and glycogen catabolism ; positively controls gene expression within the glycolytic pathway ; and also csra modulates the levels of enzymes that participate directly in pep metabolism Csra是整体调控网络的调控基因,可负调控指数生长后期诱导的一些代谢途径,包括糖原的生物合成、糖原的分解代谢、糖异生,而对糖酵解的一些重要基因的表达则执行正调控功能, csra也调控直接参与pep代谢的三个酶的活性水平。
