Researchers used a novel phosphate-activation reagent, 2-MeImIm-Cl, in an improved coupling reaction to increase the yield of ADP- or ATP-containing molecules. Unlike traditional reactions, the ...

The primary functions of the proteasome are driven by a highly allosteric ATPase complex. ATP binding to only two subunits in this hexameric complex triggers substrate binding, ATPase–20S association ...

Hsp90 plays a central role in cell homeostasis by assisting folding and maturation of a large variety of clients. It is a homo-dimer, which functions via hydrolysis of ATP-coupled to conformational ...

A so-called "molecular chaperone", the protein Hsp70, carries out more functions in the maturation of proteins than previously thought. As the researchers have discovered, Hsp70 not only acts as a ...

A new study led by Rice University's Pernilla Wittung-Stafshede has revealed that protein clumps, or plaques that clog the brain, associated with Parkinson's disease are not merely waste; they can ...
