Gamma-secretase, an integral membrane protein complex, catalyzes the intramembrane cleavage of the beta-amyloid precursor protein (APP) during the neuronal production of the amyloid beta-peptide. As such, the protease has emerged as a key target for develo ...
Caspase-3 (I) is a fundamental target for pharmaceutical interventions against a variety of diseases involving disregulated apoptosis. I is active as a dimer with 2 symmetry-related active sites, each featuring a Cys-His catalytic dyad and a selectivity lo ...
Polyvinylpyrrolidone stabilized rhodium nanoparticles are highly sol. in hydroxyl-functionalized ionic liqs., providing an effective and highly stable catalytic system. In hydrogenation reactions, excellent results were obtained, and transmission electron ...
In the framework of this thesis molecular nanostructures have been engineered on surfaces and are characterized using a variety of techniques. Two types of molecules have been used: carbon nanotubes (CNT) and 4-[trans-2-(pyrid-4-yl-vinyl)] benzoic acid (PV ...
The catalytic action of nano-sized Au particles supported on hematite (Fe2O3) and magnetite (Fe3O4) is compared in the continuous gas phase hydrogenation of p-chloronitrobenzene and m-dinitrobenzene. The catalysts were prepared by deposition-precipitation ...
The contractile tail of bacteriophage T4 is a molecular machine that facilitates very high viral infection efficiency. Its major component is a tail sheath, which contracts during infection to less than half of its initial length. The sheath consists of 13 ...
The efficiency of protease inhibiting drugs is hampered by the rapid emergence of protease variants. Understanding this phenomenon requires the characterization of the salient steps of HIV-1 protease's catalytic cycle. We summarize Our investigations on th ...
As living systems understanding got better, as life could be modeled in a batch, using immortalized cells, researches in fundamental sciences found startling applications of advanced techniques on living systems. As the biomaterial field developed various ...
The serum-amyloid-P-component-like pentraxin from Limulus polyphemus, a recently discovered pentraxin species and important effector protein of the hemolymph immune system, displays two distinct doubly stacked cyclic molecular aggregations, heptameric and ...
The primary metabolic route for D-xylose, the second most abundant sugar in nature, is via the pentose phosphate pathway after a two-step or three-step conversion to xylulose-5-phosphate. Xylulose kinase (XK; EC 2.7.1.17) phosphorylates D-xylulose, the las ...
