Thiol-based redox modulation of a cyanobacterial eukaryotic-type Serine/Threonine kinase required for oxidative stress tolerance
Aims: Protein phosphorylation is a principal signalling mechanism that mediates regulation of enzymatic activities, modulation of gene expression and adaptation to environmental changes. Recent studies have shown ubiquitous distribution of eukaryotic-type...
Mitochondrial Sulfide Detoxification Requires a Functional Isoform O-Acetylserine(thiol)lyase C in Arabidopsis thaliana
In non-cyanogenic species, the main source of cyanide derives from ethylene and camalexin biosyntheses. In mitochondria, cyanide is a potent inhibitor of the cytochrome c oxidase and is metabolized by the β-cyanoalanine synthase CYS-C1, catalyzing the conversion of...
NADPH Thioredoxin Reductase C Is Localized in Plastids of Photosynthetic and Nonphotosynthetic Tissues and Is Involved in Lateral Root Formation in Arabidopsis
Plastids are organelles present in photosynthetic and nonphotosynthetic plant tissues. While it is well known that thioredoxin-dependent redox regulation is essential for leaf chloroplast function, little is known of the redox regulation in plastids of...
Characterization of the kisspeptin system in human spermatozoa
Kisspeptin, the product of the KISS1 gene, plays an essential role in the regulation of spermatogenesis acting primarily at the hypothalamic level of the gonadotropic axis. However, the presence of kisspeptin and its canonical receptor, KISS1R, in spermatozoa has not...
