阻遏

Toosendanin (〓, FW 574, TSN), a triterpenoid derivative, is an active ingredient extracted from the bark of Melia toosendan Seib et Zucc which is used in Chinese traditional medicine as an anthelmintic vermifuge against ascarids. It was demonstrated to be a selective presynaptic blocker in neuromuscular junction and central synapses.

The tests show that said antihuman VEGF ScFv is small in molecular weight, possesses strong power for penetrating tumor ittue, its immunogenicity is low, so that it possesses the tumor-resisting function.

最终获得ScFv的高效表达，经测定证实抗人VEGF ScFv分子量小、对肿瘤组织穿透力强，免疫原性低，能阻遏肿瘤血管生成的抗肿瘤作用。

In the mixed system of culture media, because of the effect of catabolite repression and synergistic mechanism between products, the degradation of succinonitrile is promoted while the degradation of alkanes is inhibited.

在培养基混合体系中，由于分解阻遏效应和降解产物的协同效应，有利于丁二腈的降解而对烷烃降解不利。

A conclusion can be drawn that tryptopanase expressed only by constructed plasmid during "catabolite repression".

在葡萄糖存在的条件下由于分解代谢产物阻遏，基因组上的色氨酸酶基因不表达，加入IPTG只表达质粒上的基因，如果在合适条件下测得色氨酸酶活性，则可以证明质粒上的基因能表达出有活性的色氨酸酶。

The second part in this paper, an integrated model includes catabolite repression, inducer exclusion, lactose hydrolysis to glucose and galactose, and synthesis and degradation of allolactose.

Bacteria often sequentially utilize coexisting carbohydrates in environment and firstly select the one easiest to metabolization. This phenomenon is known as Carbon catabolite repression.

细菌在多种碳源共存的环境中优先利用一种的现象被称为分解代谢产物阻遏效应。

Hence, the exponential feeding mode of nutrients was carried out to control the catabolite repression by limiting the specific cell growth rate.

指数流加结果显示，通过限制细胞的比生长速率，可将阻遏作用控制在较低水平，酶产量得到了大幅度提高，是分批发酵酶产量的7.9倍，达到2565U/mL。

The detection of metabolic intermediates of glycolysis in cell demonstrated that the concentration of FDP and ATP increased abnormally when LM was added. So, the LM had an important part in the carbon catabolite repression of γ-CGTase fermentation.

对细胞内的糖酵解中间产物进行检测后发现，1，6-二磷酸果糖和ATP的含量在添加直链麦芽低聚糖后异常增加，所以直链麦芽低聚糖在B.macorous WSH02-06合成γ-CGT酶的过程中对产酶起到分解代谢阻遏效应。
