分子伴侣这类蛋白首先由Horwich在19年发现。分子伴侣的主要作用是辅助部分折叠或不正确折叠的蛋白质,加速正确折叠的进行或提供折叠发生所需的微环境。要注意分子伴侣本身并不携带靶蛋白折叠的任何信息,它不能改变靶蛋白的构象。具体作用过程你可以找几本生化书看看,一般都有介绍大肠杆菌的分子伴侣DnaK和DnaJ是如何工作的。

>Horwich在19年发现
molecular chaperone或protein chaperone
比19早多了吧
维基百科这麽说的,
History
The investigation of chaperones has a long history.[20] The term `molecular chaperone` appeared first in the literature in 1978, and was invented by Ron Laskey to describe the ability of a nuclear protein called nucleoplasmin to prevent the aggregation of folded histone proteins with DNA ring the assembly of nucleosomes.[21] The term was later extended by R. John Ellis in 1987 to describe proteins that mediated the post-translational assembly of protein complexes.[22] In 1988, it was realised that similar proteins mediated this process in both prokaryotes and eukaryotes.[23] The details of this process were determined in 19, when the ATP-dependent protein folding was demonstrated in vitro.[24]

在蛋白质折叠过程中,分子伴侣通过抑制新生肽链不恰当的聚集并排除与其他蛋白质不合理的结合,协助多肽链的正确折叠。
