S-nitrosylation of NADPH oxidase regulates cell death in plant
WebMar 1, 2024 · In the multilayered plant immune system, the superoxide (O 2 •–)-generating NADPH oxidase, RBOHD, is a key enzyme involved in ROS generation. In addition to dual and opposite regulation by nitric oxide (NO) and hydrogen sulfide (H 2 S) involved in RBOHD activity through post-translational modifications (PTMs), such as S-nitrosation (negative) … WebMoreover, sustainable H 2 S accumulation drives persulfidation of the NADPH oxidase RESPIRATORY BURST OXIDASE HOMOLOG PROTEIN D (RBOHD) at Cys825 and Cys890, enhancing its ability to produce reactive oxygen species. Physiologically, s-persulfidation-induced RBOHD activity is relevant to ABA-induced stomatal closure. morris hospital billing
Hydrogen sulfide signaling in plant adaptations to adverse …
WebIn plants, a major driver of persulfidation is hydrogen sulfide (H 2 S), a gaseus molecule that is produced in the cytosol by cysteine-degrading enzymes 123. ABA triggers persulfidation of RBOHD. Persulfidation of RBOHD is abolished in plants expressing RBOHD C825A/C890A and those plants also exhibit reduced ROS production following ABA ... WebDec 30, 2024 · In addition to dual and opposite regulation by nitric oxide (NO) and hydrogen sulfide (H 2 S) involved in RBOHD activity through post-translational modifications (PTMs), such as S-nitrosation (negative) and persulfidation (positive), respectively, RBOHD also contains unique conserved sites that can be phosphorylated by protein kinases, such as … WebApr 12, 2024 · Cysteine persulfidation modulates protein structure, localization, intermolecular interactions and enzyme activities 123.
