periplasm

The periplasm of eggs included two layers .

甜菜夜蛾卵的周质分两层；

The molecular mass of expression product was about 45 ku . It was mainly located in the periplasm .

表达产物的分子质量约为45ku，主要位于周质腔中。

The manganese protein is then transported to the periplasm having first trapped its manganese .

而后锰蛋白转移到细胞外周质，开始对锰原子进行捕获。

The secretion of recombinant protein to periplasm or extracellular medium has more advantages than the expression intracellular as inclusion bodies .

重组蛋白分泌到周质空间或胞外培养基中较之在胞内以包含体形式表达有许多优势。

Fusion expression protein amounted to 66.6 % of the total bacterial periplasm protein after induced with IPTG for 3 h at 37 ℃ .

在37℃诱导表达3h后，其融合分泌表达蛋白可占细菌周质总蛋白的66.6%。

Some spoke-like fine strands originating from the departed periplasm and stretching towards cell wall could be observed even after plasmolysis .

经历了质壁分离后，在根冠细胞仍然可以观察到许多从撤退的周质出发向细胞壁辐射的纤丝。

Plasmid pET-22b ( + ) can deliver heterologous protein into the periplasm of E. coli cells , this mode is beneficial to purify protein .

质粒pET-22b（+）能将外源蛋白分泌到大肠杆菌细胞周质中，有利于分离纯化目的蛋白。

Soluble Fab which was expressed in the periplasm of E. coli showed specific binding to HBsAg . These suggest that the phage antibodies are specific anti HBsAg .

构建了可溶性Fab段表达载体，显示出在细菌中表达的Fab段抗体与HBsAg特异性结合，这说明所筛选出来的噬菌体抗体具有抗HBsAg的特异性。

Results The soluble single chain antibody against TSI was expressed in the supernatant and periplasm , which was about 30 KDa and had activity of anti TSI .

结果抗TSI单链抗体可溶性表达于细菌培养上清和周质间隙，大小约30KDa，具有抗TSI活性。

This method can release periplasmic proteins of E.coli from the periplasm , but if PhoA is anchored in the membrane , it will not be released .

这种方法能够将周质蛋白从周质释放出，但是如果PhoA被锚定在膜上，就不会被释放。

Based on these observations , we propose that the periplasmic proteins have been evolved to resist the formation of aggregates when subjected to various denaturing conditions and molecular chaperones may thus not be needed in periplasm .

根据这些发现，我们提出假说：膜间质蛋白在恶劣环境条件的选择压力下进化出对各种变性条件所诱导聚集的抗性，而不需要分子伴侣蛋白的有效保护。

Disulfide bond formation protein A , DsbA , existing in the periplasm of E. coli , is a protein disulfide isomerase ( PDI ), which assists folding of the disulfide bond containing proteins to achieve biological activities .

二硫键形成蛋白A（DisulfidebondformationproteinA，DsbA）是大肠杆菌周质胞腔中辅助多种含有二硫键的蛋白质正确折叠并具有生物学活性的一种二硫键异构酶。
