Breaking the Cycle, Cholesterol Cycling, and Synapse Damage in Response to Amyloid-ß [PDF]
Soluble amyloid-β (Aβ) oligomers, a key driver of pathogenesis in Alzheimer disease, bind to cellular prion proteins (PrPC) expressed on synaptosomes resulting in increased cholesterol concentrations, movement of cytoplasmic phospholipase A2 (cPLA2) to ...

NMR Line Shape Analysis of a Multi-state Ligand Binding Mechanism in Chitosanase [PDF]
Chitosan interaction with chitosanase was examined through analysis of spectral line shapes in the NMR HSQC titration experiments. We established that the substrate, chitosan hexamer, binds to the enzyme through the three-state induced-fit mechanism with

Expanding the Toolkit for the Serine Hydrolases
In this issue of Chemistry & Biology, Cognetta et al. (2015) describe new pharmacological tools, including N-hydroxyhydantoin-containing carbamate inhibitors and an activity-based probe, for palmitoyl protein thioesterase 1 and alpha, beta-hydrolase domain-4 that expand the toolkit for the serine hydrolases.

Properties of epoxide hydrolase from the yeast Rhodotorula glutinis [PDF]
Epoxide hydrolases are ubiquitous enzymes that can be found in nearly all living organisms. Some of the enzymes play an important role in detoxifying xenobiotic and metabolic compounds.

Lipase catalysed kinetic resolution of racemic 1,2-diols containing a chiral quaternary center [PDF]
Optically active 1,2-diols are valuable buildings blocks in organic synthesis. In the present paper, a set of racemic 1,2-diols with an ester functional group are prepared, starting from -ketoesters in a three-step procedure with moderate yields.

Chitinase Activities in Wheat and Its Relative Species
Defense components such as chitinases (EC 3.2.1.14) are crucial for plants to cope diseases. Despite of that the pattern and activities of these enzymes in agronomically important Triticale is unexplored.

EPR Studies on the Mono- and Dicobalt(II)-Substituted Forms of the Aminopeptidase from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e. Insight into the Catalytic Mechanism of Dinuclear Hydrolases [PDF]
The structure and function of the prototypical dinuclear hydrolase, namely, the aminopeptidase from Aeromonas proteolytica (AAP), was probed by EPR spectroscopy of the mono- and dicobalt(II)-substituted derivatives.
