The Dual Role of Active Site Hydroxylated Residue in Peroxiredoxin Sulfinylation Catalysis Open
Aims: Peroxiredoxins (Prx) are ubiquitous Cys peroxidases regulated by sulfinylation, a modification that occurs when the sulfenic acid generated on the catalytic Cys by peroxide reduction reacts with a second molecule of per…

TRIMETHYLGUANOSINE SYNTHASE1 mutations decanalize female germline development in Arabidopsis Open
Summary Here, we report the characterization of a plant RNA methyltransferase, orthologous to yeast trimethylguanosine synthase1 (Tgs1p) and whose downregulation was associated with apomixis in Paspalum grasses. Using phylogenetic analyses…

Rhodanese-Fold Containing Proteins in Humans: Not Just Key Players in Sulfur Trafficking Open
The Rhodanese-fold is a ubiquitous structural domain present in various protein subfamilies associated with different physiological functions or pathophysiological conditions in humans. Proteins harboring a Rhodanese domain are diverse in …

A Redox-Sensitive Cysteine Is Required for PIN1At Function Open
Parvulins are ubiquitous peptidyl-prolyl isomerases (PPIases) required for protein folding and regulation. Among parvulin members, Arabidopsis PIN1At, human PIN1, and yeast ESS1 share a conserved cysteine residue but differ by the presence…

The cytosolic<i>Arabidopsis thaliana</i>cysteine desulfurase ABA3 delivers sulfur to the sulfurtransferase STR18 Open
The biosynthesis of many sulfur-containing molecules depends on cysteine as a sulfur source. Cysteine desulfurase (CD) and rhodanese (Rhd) domain-containing protein families participate in the trafficking of sulfur for various metabolic pa…

Novel insights into the diversity of the sulfurtransferase family in photosynthetic organisms with emphasis on oak Open
Summary Sulfurtransferases ( STR s) constitute a large and complex protein family characterized by the presence of a rhodanese domain and implicated in diverse molecular and signaling processes as sulfur carriers. Although sulfurtransferas…

Atypical protein disulfide isomerases (PDI): Comparison of the molecular and catalytic properties of poplar PDI-A and PDI-M with PDI-L1A Open
Protein disulfide isomerases are overwhelmingly multi-modular redox catalysts able to perform the formation, reduction or isomerisation of disulfide bonds. We present here the biochemical characterization of three different poplar PDI isof…

Live-cell analysis of DNA methylation during sexual reproduction in <i>Arabidopsis</i> reveals context and sex-specific dynamics controlled by noncanonical RdDM Open
Cytosine methylation is a key epigenetic mark in many organisms, important for both transcriptional control and genome integrity. While relatively stable during somatic growth, DNA methylation is reprogrammed genome-wide during mammalian r…
