据观察,分子伴侣的可用性不足是重组蛋白生产中正确蛋白质折叠的主要瓶颈。因此,共同生产选定的细胞伴侣与外源多肽是增加细菌细胞工厂中正确折叠的重组蛋白产量的常见方法。然而,处理抗折叠蛋白种类的折叠调节剂数量不平衡可能反而会引发不需要的蛋白水解活性,这对重组蛋白的稳定性、质量和产量是有害的。这篇小型评论总结了最近观察到的伴侣相关负面副作用,主要集中在 DnaK 和 GroEL 组上,当使用这些蛋白质作为折叠辅助剂时。这些事件是在细胞质量网络的复杂性以及蛋白质错误折叠引发的生理反应的复杂性的背景下讨论的。
Insufficient availability of molecular chaperones is observed as a major bottleneck for proper protein folding in recombinant protein production. Therefore, co-production of selected sets of cell chaperones along with foreign polypeptides is a common approach to increase the yield of properly folded, recombinant proteins in bacterial cell factories. However, unbalanced amounts of folding modulators handling folding-reluctant protein species might instead trigger undesired proteolytic activities, detrimental regarding recombinant protein stability, quality and yield. This minireview summarizes the most recent observations of chaperone-linked negative side effects, mostly focusing on DnaK and GroEL sets, when using these proteins as folding assistant agents. These events are discussed in the context of the complexity of the cell quality network and the consequent intricacy of the physiological responses triggered by protein misfolding.
