蛋白质过硫化修饰研究进展

Research progress in protein persulfidation

摘要:

过硫化修饰在保护蛋白质的正常功能和信号传递过程中起着重要作用，对维持细胞的正常生理代谢平衡、保护细胞抵抗氧化应激及硫稳态调控等方面具有重要影响。本文综述了硫化氢、活性硫及半胱氨酸代谢的内在关联以及硫稳态调控，阐述了蛋白质过硫化修饰的机制及在微生物硫稳态调节中的作用，对未来的研究方向和趋势提供了新的思路。

Abstract:

Persulfidation plays a role in protein functioning and signaling, maintaining the physiological and metabolic balance of cells, protecting cells from oxidative stress, and regulating sulfur homeostasis. This article summarized the internal relationship of hydrogen sulfide, reactive sulfur species, and cysteine metabolism, expounded the mechanism of sulfur homeostasis regulation, and introduced the role of persulfidation in microbial sulfur homeostasis, providing new thoughts for the future research.
