“…Trxs 100 are widely distributed proteins with a main function to reduce specific S-S group through a 101 conserved motif CxxC (Gelhaye et al, 2005;Meyer et al, 2005). Trxs alter the activity of 102 interacting target proteins via thiol-based redox modifications (Rouhier et al, 2015). A number of 103 potential Trx targets have been identified using proteomic approaches (Montrichard et al, 2009 Santos and Rey, 2006), transcription factors for gene expression (Murmu et al, 2010;Viola et al, 107 2013), and hormonal receptors for signal transduction (Tada et al, 2008 (Balmer et al, 2004;Yoshida et al, 2013;Braun et al, 2014;Dröse et al, 2014).…”

XS. Thioredoxin-mediated ROS homeostasis explains natural variation in plant regeneration.The authors have acknowledged that errors were made in the creation of some of the figures for this article. The description of the figure corrections in detail is shown as follows. Both original and corrected figures are provided for ease of comparison.In the original Figure 3, the gel blot images in Figure 3B and 3D were overly contrasted and tightly cropped. The upper image in Figure 3B and images in Figure 3D were combined from two gels, respectively. In the corrected Figure 3, the images of Figure 3B and 3D are appropriately cropped and provided without any manipulations of contrast. Three white lines have been inserted to separate the upper image in Figure 3B and images in Figure 3D, respectively. The legend of the figure has been changed accordingly for clarity.In the original Figure 5, the gel blot image in Figure 5A and 5B was overly contrasted and tightly cropped. In the corrected Figure 5, the images of Figure 5A and 5B are appropriately cropped and provided without any manipulations of contrast. The figure legend has not been changed.

“…Several genetic studies aiming to identify functions of TRX and Glutaredoxin (GRX) in single mutants have been performed. Such approaches have assigned some functions for specific glutaredoxin and thioredoxins (reviewed by Rouhier et al, 2015). Nevertheless, not clear phenotypes have been detected, for most cytosolic TRX and GRX, which can be attributed to functional redundancies between members of large multigenic families (Meyer et al, 2008).…”

“…GSH is a tripeptide (Glu-Cys-Gly) and is present at millimolar concentrations in plant cells, thereby acting as a buffer against oxidative stress and maintaining thiol homeostasis (Zaffagnini et al, 2012b;Rouhier et al, 2015). GSH becomes oxidized (GSSG) by acting as an electron donor to reduce oxidized Cys or Met residues, and GSSG can be reduced back to GSH by a family of glutaredoxins.…”

Update: Post-translational protein modifications in plant metabolism

ORCID ID: 0000-0001-9536-0487 (K.J.v.W.).Posttranslational modifications (PTMs) of proteins greatly expand proteome diversity, increase functionality, and allow for rapid responses, all at relatively low costs for the cell. PTMs play key roles in plants through their impact on signaling, gene expression, protein stability and interactions, and enzyme kinetics. Following a brief discussion of the experimental and bioinformatics challenges of PTM identification, localization, and quantification (occupancy), a concise overview is provided of the major PTMs and their (potential) functional consequences in plants, with emphasis on plant metabolism. Classic examples that illustrate the regulation of plant metabolic enzymes and pathways by PTMs and their cross talk are summarized. Recent large-scale proteomics studies mapped many PTMs to a wide range of metabolic functions. Unraveling of the PTM code, i.e. a predictive understanding of the (combinatorial) consequences of PTMs, is needed to convert this growing wealth of data into an understanding of plant metabolic regulation.The primary amino acid sequence of proteins is defined by the translated mRNA, often followed by Nor C-terminal cleavages for preprocessing, maturation, and/or activation. Proteins can undergo further reversible or irreversible posttranslational modifications (PTMs) of specific amino acid residues. Proteins are directly responsible for the production of plant metabolites because they act as enzymes or as regulators of enzymes. Ultimately, most proteins in a plant cell can affect plant metabolism (e.g. through effects on plant gene expression, cell fate and development, structural support, transport, etc.). Many metabolic enzymes and their regulators undergo a variety of PTMs, possibly resulting in changes in oligomeric state, stabilization/degradation, and (de)activation (Huber and Hardin, 2004), and PTMs can facilitate the optimization of metabolic flux. However, the direct in vivo consequence of a PTM on a metabolic enzyme or pathway is frequently not very clear, in part because it requires measurements of input and output of the reactions, including flux through the enzyme or pathway. This Update will start out with a short overview on the major PTMs observed for each amino acid residue (Table I), followed by a brief discussion of techniques for the characterization of protein PTMs, including determination of the localization within proteins (i.e. the specific residues) and occupancy. Challenges in dealing with multiple PTMs per protein and cross talk between PTMs will be briefly outlined. We then describe the major physiological PTMs observed in plants as well as PTMs that are nonenzymatically induced during sample preparation (Table II). Finally, this Update is completed with a number of well-studied, classical examples of the regulation of plant metabolism by PTMs, in particular for enzymes in primary metabolism (Calvin cycle, glycolysis, and respiration) and the C4 shuttle accommodating photosynthesis in C4 plants (Table III). As will be ev...
