Hypoxanthine‐guanine phosphoribosyltransferase (HGPRT) is a key enzyme in the purine salvage pathway. Here, the reverse reaction of HGPRT from the thermophilic bacterium Hungateiclostridium thermocellum was studied in the presence of IMP and pyrophosphate. As for the human enzyme, the bacterial HGPRT was activated by guanine. Furthermore, guanine was found to operate as both an activator and an inhibitor...
Control of the coefficient of thermal expansion (CTE) of polymeric materials is critical in many applications, particularly the electronics industry where CTE mismatches have caused failures. In theory, adding exfoliated nanoplatelets with high aspect ratios would offer an effective solution for reducing CTE, but reported results have not been compelling due to poor dispersion. In this study, α‐zirconium...
