Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Properties and Performance of High-Purity Thermal Barrier Coatings

, 2007
It was found that the content of impurity oxides in 7YSZ, such as SiO2 and Al2O3, has a significant effect on coating sintering resistance and phase stability of 7YSZ thermal barrier coatings (TBCs).
