Nevertheless, no homologues of typical molecular chaperones have so far been found in periplasm, and the recently reported chaperone activities of periplasmic protein disulfide isomerase and peptidyl pro-lyl isomerase seem to be too weak to satisfy such assumed needs.

虽然膜间质中的蛋白二硫键异构酶和脯氨酸顺反异构酶最近被报导具有分子伴侣活性，但是这种活性的检测使用的不是天然的膜间质蛋白，而且没有捕获到复合物的形成，因此看起来仍不能够满足前面分析的对膜间质蛋白保护的需求。

To obtain thermostable xylose isomerase, the gene xylA from an extremely thermophilic bacterium,Thermus thermophilus HB8 was cloned and its product was overexpressed in Escherichia coli BL21(DE3) with expression vector pET22b.

为获得具有高热稳定性的木糖异构酶，运用基因工程技术，从嗜热栖热菌Thermus thermophilus HB8中克隆到嗜热木糖异构酶基因xylA。

We also strongly suggest that the recently reported chaperone acitivity of periplasmic PDI-ase and PPIase assayed by traditional substrate should be reexamined using periplasmic proteins as substrate due to the significant difference between those two classes of proteins, the possible chaperone fuctions of PDIase and PPIase in vivo should be reappraised.

同时，由于本实验结果显示膜间质蛋白与常用的分子伴侣测活底物蛋白在聚集行为上存在极显著的区别，我们建议对最近报导的膜间质蛋白二硫键异构酶和脯氨酸顺反异构酶分子伴侣活性以膜间质蛋白为底物再进行验证，对其在膜间质是否发挥分子伴侣功能重新慎重考虑。

In our results, we found four proteins have isoforms; these proteins are peptidyl-prolyl cis-trans isomerase A, prohibitin, enolase 1, myeloperoxidase precursor.

同时，我们发现肽基辅胺酸顺反异构酶（peptidyl-prolyl cis-trans isomerase A）、抑制素、烯醇酶（enolase 1）、过氧化骨髓酶有异构体的产生。

By using lysozyme, RNase A and protein disulfide isomerase as model proteins, we present a hypothesis that protein cross-linking can be accomplished in three concerted steps:(1) a change in protein conformation;(2) formation of interchain disulfide bonds; and (3) formation of interchain isopeptide cross-links.

我们以溶菌酶、核糖核酸酶A和蛋白质二硫键异构酶为模型对异肽键进行了体外详细的研究，提出了解释异肽键形成机理的假说：1蛋白质发生构象变化包括二级结构的改变；2蛋白质形成分子间二硫键：3二硫键的形成帮助蛋白质形成了分子间异肽键。

He analysis of the category and function of TCB stress inducible proteins showed that different groups of proteins were induced by 5 mg L^(-1) TCB stress. They are detoxification enzymes (including esterase, aldo/keto reductases, and glutathione S-transferase), cell wall compound metabolism related enzymes (including UDP-glucose protein transglucosylase and GDP-mannose 3,5-epimerase 1), phytohormone metabolism and regulation related enzymes or proteins (including aci-reductone dioxygenase 4, beta-glucosidase, two members of pathogenesis-related proteins from family 10), primary and secondary metabolism regulative enzymes (including translational elongation factor Tu, cytosolic orthophosphate dikinase, triosephosphate isomerases, alanine aminotransferase, and isoflavone reductase).
