ProteomicsNew insights on the role of HCN in root hair elongation through single cell proteomics.
In order to identify the possible protein targets of cyanide in the regulation of root hair, we have carried out a single cell proteomic approach to characterize the protein atlas in wild type root hair cells compared to the cas-c1 mutant cells. Root hair specific cells were obtained from isolated p...

ProteomicsHCN regulates cellular processes through posttranslational modification of proteins by S-cyanylation
Hydrogen cyanide (HCN) is coproduced with ethylene in plant cells and primarily enzymatically detoxified by the mitochondrial ß-cyanoalanine synthase (CAS-C1). Permanent or transient depletion of CAS-C1 activity in Arabidopsis results in physiological alterations in the plant that suggest that the f...

ProteomicsProteomic analysis in Arabidopsis tissues reveals hydrogen cyanide regulation of intracellular processes through posttranslational modification of proteins by S-cyanylation
Hydrogen cyanide (HCN) is co-produced with ethylene in plant cell and enzymatically detoxified mainly by the mitochondrial ß-cyanoalanine synthase (CAS-C1). Permanent or transient depletion of CAS-C1 activity in Arabidopsis results in physiological alteration in the plant that point to the function...

TranscriptomicsAn O-acetylserine(thiol)lyase homolog regulates cysteine homeostasis in Arabidopsis thaliana
Cysteine occupies a central position in plant metabolism due to its biochemical functions. Arabidopsis thaliana cells contain different O-acetylserine(thiol)lyase (OASTL) enzymes that catalyze the biosynthesis of cysteine. Because they are localized in the cytosol, plastids and mitochondria, this re...

TranscriptomicsExogenous Sulfide Reverses the Alteration of Transcriptional Profiling of the des1-1 Mutant (Arabidopsis thaliana)
Arabidopsis thaliana cells contain different O-acetylserine(thiol)lyase (OASTL) enzymes that catalyze the biosynthesis of cysteine. Recently, we have deeply investigated about one of the minor OASTL-like protein located in the cytosol, named DES1, highlighting some important clues about its metaboli...

TranscriptomicsDepleting cytosolic cysteine compromises the antioxidant capacity of the cytosol in Arabidopsis thaliana
Plant cells contain different O-acetylserine(thiol)lyase (OASTL) enzymes involved in Cys biosynthesis and located in different subcellular compartments. These enzymes are made up of a complex variety of isoforms resulting in different subcellular Cys pools. To unravel the contribution of cytosolic C...

ProteomicsPersulfidated subproteome reveals the regulation of protein function by hydrogen sulfide in diverse biological processes and nuclear translocation of glyceraldehyde-3-phosphate dehydrogenase in plants.
Hydrogen sulfide-mediated signaling pathways regulates many physiological andpathophysiological processes in mammalian and plant systems. The molecular mechanism bywhich hydrogen sulfide exerts its action involves the oxidative post-translational modificationof cysteine residues to form a persulfida...

TranscriptomicsA novel S-sulfocysteine synthase essential for chloroplast function in Arabidopsis thaliana
In bacteria, the biosynthesis of cysteine is accomplished by two enzymes that are encoged by the cysK and cysM genes. CysM is also able to incorporate thiosulfate to produce S-sulfocysteine. In plant cells, the biosynthesis of cysteine occurs in the cytosol, mitochondria and chloroplasts. Chloroplas...
