查询词典 biosynthetic

Ornithine decarboxylase, a rate-determining enzyme of the polyamine biosynthetic pathway, is involved in the control of cell cycle, differentiation, cell growth and apoptosis. Previous studies described that protein kinase Cd regulates ODC activity. In this thesis, human leukemia cell line, HL60 cell, was used for the treatment with a specific PKCd inhibitor, rottlerin, to measure the effects on cell growth.

鸟胺酸去羧化（ornithine decarboxylase，ODC）为多胺酸起始与决定反应速率的酵素，对细胞周期、细胞生长、分化及细胞凋亡扮演一重要角色；在寻找肿瘤治疗及预防药物研究中，纯化植物天然物质是其中来源之一，研究者筛选药物时，测定对鸟胺酸去羧化活性是否具抑制效果是一个重要的试验。

In the process of nature evolution, plants have evolved to overcome pathogenic infection, especially for virus, which relies on the plant＇s biosynthetic and energy-producing capabilities.

在自然演化发展的过程中，植物进化产生了一系列抗外界微生物侵染的能力，其中包括抵抗依靠植物的生物合成及能量的病毒。

Naturally occurring terpenes constitute the largest group of natural products with complicated and variable structures and a great number of important biological activities.2-Methyl-D-erythreitol 4-phosphate pathway is a newly found and established biosynthetic route for terpenoids and all the enzymes involved in this pathway can be used as targets for the screening of new antibiotics.

萜类化合物构成了最大的一个天然产物家族，结构复杂多变，且有许多重要的生理活性。2-甲基-D-赤藓糖醇4-磷酸途径是近年来发现并建立的一条萜类化合物的生物合成途径，其中所涉及到的酶均可作为靶标来进行新抗菌素的筛选。

This article has carried on an overview of biosynthetic pathway of terpenoids and the HMG-CoA reductases.

Attenuation vs repression The trp operon is regulated by both repression(which determines whether transcription will occur or not)and attenuation.Other operons for amino acid biosynthetic pathways may also be regulated by both repression and attenuation or only by attenuation.

弱化作用与阻遏作用的比较 trp操纵子同时受到弱化作用和阻碍作用的调控，其他氨基酸生物合成途径的操纵子也可能受弱化作用和阻碍作用的调控，或者仅有弱化作用调控。

In addition, plant/T-DNA junction sequence analysis excluded the possibility that insertion of T-DNA into anthocyanin genes had inactivated the anthocyanin biosynthetic pathway in white-flowered tobacco plants.

此外，植物/T-DNA接合序列分析亦排除产生白色花色的原因是由於T-DNA插入植物色素合成相关基因导致该基因丧失活性的可能性。
