Arabidopsis S-Sulfocysteine Synthase Activity Is Essential for Chloroplast Function and Long-Day Light-Dependent Redox Control
(American Society of Plant Biologists, 2010)
In bacteria, the biosynthesis of Cys is accomplished by two enzymes that are encoded by the cysK and cysM genes. CysM is also able to use thiosulfate as a substrate to produce S-sulfocysteine. In plant cells, the biosynthesis ...

S-sulfocysteine synthase function in sensing chloroplast redox status
(Taylor & Francis, 2013)
The minor chloroplastic O-acetylserine(thiol)lyase isoform encoded by the CS26 gene in Arabidopsis thaliana has been described as an S-sulfocysteine synthase enzyme that plays an important role in chloroplast function. ...

Hydrogen sulfide regulates the cytosolic/nuclear partitioning of glyceraldehyde-3-phosphate dehydrogenase by enhancing its nuclear localization
(Oxford University Press, 2017)
Hydrogen sulfide is an important signaling molecule comparable with nitric oxide and hydrogen peroxide in plants. The underlying mechanism of its action is unknown, although it has been proposed to be S-sulfhydration. This ...

Biochemical characterization of the amylase activity from the new haloarchaeal strain haloarcula sp. Hs isolated in the odiel marshlands
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Alpha‐amylases are a large family of α,1‐4‐endo‐glycosyl hydrolases distributed in all kingdoms of life. The need for poly‐extremotolerant amylases encouraged their search in extreme environments, where archaea become ideal ...

Cysteine and cysteine-related signaling pathways in arabidopsis thaliana
(Oxford University Press, 2014)
Cysteine occupies a central position in plant metabolism because it is a reduced sulfur donor molecule involved in the synthesis of essential biomolecules and defense compounds. Moreover, cysteine per se and its derivative ...

Hydrogen Sulfide Signaling in Plants: Emerging Roles of Protein Persulfidation
(Frontiers Media, 2018)
Hydrogen sulfide (H2S) has been largely referred as a toxic gas and environmental hazard, but recent years, it has emerged as an important gas-signaling molecule with effects on multiple physiological processes in both ...

Persulfidation protects from oxidative stress under nonphotorespiratory conditions in Arabidopsis
(Wiley-Blackwell, 2023)
Hydrogen sulfide is a signaling molecule in plants that regulates essential biological processes through protein persulfidation. However, little is known about sulfide-mediated regulation in relation to photorespiration. ...

Abscisic acid-triggered persulfidation of the cys protease ATG4 mediates regulation of autophagy by sulfide
(American Society of Plant Biologists, 2020)
Hydrogen sulfide is a signaling molecule that regulates essential processes in plants, such as autophagy. In Arabidopsis (Arabidopsis thaliana), hydrogen sulfide negatively regulates autophagy independently of reactive ...

S-Sulfhydration: A Cysteine Posttranslational Modification in Plant Systems
(American Society of Plant Biologists, 2015)
Hydrogen sulfide is a highly reactive molecule that is currently accepted as a signaling compound. This molecule is as important as carbon monoxide in mammals and hydrogen peroxide in plants, as well as nitric oxide in ...

Photosynthetic Adaptation to Length of Day Is Dependent on S-Sulfocysteine Synthase Activity in the Thylakoid Lumen
(American Society of Plant Biologists, 2012)
Arabidopsis (Arabidopsis thaliana) chloroplasts contain two O-acetyl-serine(thiol)lyase (OASTL) homologs, OAS-B, which is an authentic OASTL, and CS26, which has S-sulfocysteine synthase activity. In contrast with OAS-B, ...
