Arabidopsis S-Sulfocysteine Synthase Activity Is Essential for Chloroplast Function and Long-Day Light Dependent Redox Control
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 of Cys occurs in the cytosol,...
Cyclometallation and Hydrogen/Deuterium Exchange Reactions of an Arylphosphine Ligand upon Coordination to {Ir(C5Me5)}
The cyclometallated compounds [(C5Me5)Ir(X){PMe(2,6-CH2(Me)C6H3)(2,6-Me2C6H3)}] (X=Cl, H, Me) have been synthesized in high yields and their potential for C-H activation demonstrated. Subsequent functionalization of these species has provided a series of complexes...
An O-Acetylserine(thiol)lyase Homolg with L-Cysteine Desulfhydrase Activity Regulates Cysteine Homeostasis in Arabidopsis
Cysteine (Cys) occupies a central position in plant metabolism due to its biochemical functions. Arabidopsis (Arabidopsis thaliana) cells contain different O-acetylserine(thiol)lyase (OASTL) enzymes that catalyze the biosynthesis of Cys. Because they are localized in...
Ionic liquid templated TiO2 nanoparticles as a support in gold environmental catalysis
This work presents the synthesis of a nanostructured titania support and its subsequent utilization for the gold particles deposition and application in the reaction of the CO oxidation. A functionalized ionic liquid has been used as a templating agent for the...
