These chaperones also refold proteins that have become unfolded.

这些伴护蛋白也会把摊开的蛋白质再折叠回去。

AIM: To refold and biotinylate HLA A2 peptide complex in vitro .

目的：可溶性HLA A2 抗原肽复合物的体外折叠复性与生物素化。

Once present in the brain it causes normal proteins to refold into the abnormal shape.

一旦在大脑中出现，它便使正常的蛋白质打褶成异常形状。

After the peptide chain has been unfolded by heating, by exposure to low pH, or by treatment with urea, it will often spontaneously refold to the native form, this sequence is called renaturation.

肽链加热打开之后，将其置于低pH值环绕或用尿素处理，再折叠到原来的形状，这个过程叫做复体。
