ABSTRACT Hydrogen sulfide (H2S) is a versatile signaling molecule that regulates multiple physiological processes in plants, including growth and development, immunity, and stress response as well. Signaling triggered by H2S is proposed to occur via persulfidation, an oxidative post-translational modification (PTM) of cysteine residues (–SH) to persulfides (–SSH). Notwithstanding the growing body of information for the plant persulfidation proteome, the gap between the molecular mechanism of H2S and physiological functions of protein persulfidation remains large. In this mini-review, we discussed the specific regulatory mechanism of persulfidation on guard cell abscisic acid (ABA) signaling and the possible link of persulfidation, sulfenylation, and S-nitrosylation within the framework of redox-based regulation.

保卫细胞 ABA 信号中基于氧化还原的蛋白质过硫化

摘要 硫化氢 (H2S) 是一种多功能信号分子,可调节植物的多种生理过程,包括生长发育、免疫和应激反应。由 H2S 触发的信号传导被提议通过过硫化发生,这是一种半胱氨酸残基 (-SH) 到过硫化物 (-SSH) 的氧化翻译后修饰 (PTM)。尽管植物过硫化蛋白质组的信息越来越多,但 H2S 的分子机制与蛋白质过硫化的生理功能之间的差距仍然很大。在这篇小型综述中,我们讨论了过硫化对保卫细胞脱落酸 (ABA) 信号传导的具体调控机制,以及在基于氧化还原的调控框架内过硫化、亚磺酰化和 S-亚硝基化的可能联系。
