Glutathione-dependent enzymes play important protective, repair, or metabolic roles in cells. In particular, enzymes in the glutathione S-transferase (GST) superfamily function in stress responses, defense systems, or xenobiotic detoxification. Here, we identify novel features of bacterial GSTs that cleave β-aryl ether bonds typically found in plant lignin. Our data reveal several original feat...

The title compound, [Pb(C11H16O2PS2)2], is a neutral four-coordinate mononuclear complex with a distorted square-pyramidal geometry of the PbS4 core. The apical Pb(II) atom of each pyramid is 1.33059 (3) Å above the basal S4 plane. The metal atom is surrounded by two chelating dithio-phospho-nate ligands binding through the S-donor atoms. The ligands are anisobidentate as the pyramid is compris...

I examined the effects of isolation on the structure of both adult and larval dragonfly (Odonata: Anisoptera) communities forming at physically identical artificial ponds over two years. Isolation, whether measured by distance to the nearest source habitat or by connectivity to multiple sources, was significantly negatively related to the species richness of dragonflies observed at and collecte...

given a Grade D in the re-grading which compares unfavourably with their colleagues working on the in-patient unit. In common with many day hospitals, our nurses exhibit a high degree of clinical autonomy and are responsible for a substantial caseload of community based patients. They must liaise with families, community carers and the psychiatric firms to which the patients are attached. In ad...

The Ni-catalysed cross-coupling of aryl ethers is a powerful method to forge new C−C and C−heteroatom bonds. However, the inert C(sp2)−O bond means that canonical mechanism relies on oxidative addition ether Ni0 centre thermodynamically kinetically unfavourable, which suggests alternative mechanisms may be involved. Here, we provide spectroscopic structural insights into anionic pathway, format...

An efficient procedure and green route has been developed by using eco-friendly green synthesized palladium nanoparticles (Pd-NPs) as reusable heterogeneous nanocatalyst (Pd@nanocat) for the synthesis of diaryl ethers from the cross coupling reaction of the aryl halides with the phenol in the presence of dimethylsulfoxide (DMSO) as a solvent at 110 oC under natural ligand condition capped Pd-NP...
