We make chloroacetylaion to N-terminal of Asp, and then convert this compound to GD dipeptide by aminolysis. Followed the lipase -catalyzed peptide synthesis of RGD in aqueous water-miscible organic cosolvent is studied. We set up a new efficient reaction method to synthesize RGD tripeptide. The problem that peptide containing polar amino acid can not be synthesized readily in organic solvent was solved. We offer a new experimental proof for PPL-catalyzed peptide synthesis and make a more general analysis for the effect of some factors in theory.

采用氯乙酰基保护天冬氨酸，然后进行氨解生成GD二肽，利用猪胰脂肪酶催化合成RGD三肽，着重解决了亲水氨基酸/肽片段底物的溶解性与合成产率低的问题，建立了一种新的有效合成RGD三肽的反应模型，并探索解决了极性较强的氨基酸的酶促肽合成的问题，对脂肪酶催化合成肽的影响因素从理论上作了较全面的分析，为肽片段的缩合反应提供了一种新思路。

The result has demonstrated that a kind of X-Pro dipeptidase-like protein which is capable of hydrolyzing G-type organophosphate exists in Arabidopsis thaliana, but no enzyme which can degrade OPs such as methamidophos exists.

结果表明，拟南芥中存在可降解G类有机磷的氨酰基脯氨酸二肽酶的类似蛋白，未发现存在可降解甲胺磷等有机磷农药的酶类。

The study performed by the New England Journal of Medicine suspects that the risk of death is increased by nearly 50 percent in patients who are administered Trasylol instead of alternative mediations.

这项研究由美国的新英格兰医学杂志嫌疑人，死亡的危险增加了近50%的病人抑肽酶经管而非替代斡旋。

The study performed by the New England Journal of Medicine suspects that the risk of death is increased by nearly 50 percent in patients who are administered Trasylol instead of alternative mediations.

这项研究由新英格兰医学杂志的嫌犯死亡的危险增加近百分之五十的病人经管抑肽酶不是替代斡旋。

Objective To Study the debittering effect of aminopeptidase from Bacillus subtilis on soy protein hydrolysate.

目的研究从豆腐乳中筛选到的一种枯草芽孢杆菌所产的氨肽酶脱除大豆蛋白质水解物苦味的效果。

These results showed that the increase of endopeptidase activity and the decrease of protein content are likely to the production of H2O2 under Al3＋ stress.

Al3＋胁迫下小麦幼苗叶片中的内肽酶活性升高和可溶性蛋白质含量下降的原因之一是产生了活性氧—H2O2。

The results showed that obvious differences between the two cultivars were obtained in contents of soluble protein and free amino acid,and endopeptidase activity during flower opening and senescence,although...

结果表明，两品种可溶性蛋白质和游离氨基酸含量及内肽酶活性在开花衰老进程中的变化趋势基本一致，但是在量上差异非常明显。

In the lungs, mainly derived from alveolar macrophages, airway epithelial cells, lymphocytes and neutrophil aggregation, IL-8 may tolerance serum and effusions Endopeptidase degradation, there a long time, which can be accumulated in local, in response to a sustained effect, enlarged inflammatory response .

在肺部，其主要来源于肺泡巨噬细胞，气道上皮细胞，淋巴细胞和聚集的中性粒细胞，IL-8可耐受血清和渗出液中肽酶的降解，存在时间长，因而能在局部累积，在反应中发挥持续效应，放大了炎症反应。

Cut rose'Samantha',a cultivar with strong tolerance to water deficit stress, and 'Belami',a cultivar with middle range tolerance were used to investigate the changes of contents of soluble protein and free amino acid,and endopeptidase activity in petals during flower opening and senescence.

以切花月季耐失水胁迫品种'萨蔓莎'和中度耐失水胁迫品种'贝拉米'为试材，研究了采后开花衰老进程中可溶性蛋白质和游离氨基酸含量及内肽酶活性和种类的变化。

N-terminal analysis showed that the signal peptide had been removed indicating that the insect cells posses the enzymatic activity necessary to cleave the pro-α-factor leader region from the fusion protein at the carboxy side of Lys-Arg dibasic residues, which is the cleavage site recognized by KEX2 endopeptidase in yeast cells.

该位点在酵母细胞中是由KEX2基因编码的内肽酶切割的。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
