The metal centres in metalloenzymes and molecular catalysts are responsible for the rearrangement of atoms electrons during complex chemical reactions, they enable selective pathways charge spin transfer, bond breaking/making formation new molecules. Mapping electronic structural changes at sites reactions gives a unique mechanistic insight that has been difficult to obtain date. development X-...
Enzymatic and homogeneous catalysis offer complementary means to produce enantiopure products. Incorporation of achiral, biotinylated aminodiphosphine-rhodium complexes in (strept)avidin affords enantioselective hydrogenation catalysts. A combined chemogenetic procedure allows the optimization of the activity and the selectivity of such artificial metalloenzymes: the reduction of acetamidoacryl...
The metal-binding preferences of most metalloproteins do not match their metalrequirements. Thus, metallation of an estimated 30% of metalloenzymes is aided by metaldelivery systems, with ~25% acquiring preassembled metal-cofactors. The remaining ~70% are presumed to compete for metals from buffered metal-pools. Metallation is further aided by maintaining the relative concentrations of these po...
Cupper Oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. The structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. SEM images show gradual development of hierarchical structures of copper oxide with different morphology. In order to study the effect of reaction time and te...
