In literature, microporous aluminoborate with 18- and 24-octahedral-atom channels have been synthesized and nominated as PKU-1 and PKU-2. [1, 2] Preliminary redox catalytic property has also been investigated with Cr-incorporated PKU-1.[3].Herein, we systematically study the synthesis conditions for the Cr-substitution and find the doping limit is 5 atom%, which is quite high in microporous materials.

Background: Elongator is a multiprotein complex that exhibits acetyltransferase activity. Results: In the subcomplex Elp4-6, Elp6 acts as a bridge to assemble Elp4 and Elp5, and each subunit adopts a similar RecA-ATPase-like fold. Conclusion: Subcomplex Elp4-6 formsa hexameric ring-shaped structure that is important for histone H3 binding. Significance: This finding may shed light on holo-Elongator complex assembly and its substrate recognition.

The solid solutions Sr4-xCaxGaTaO8(x=0,1,2,3,4) have been synthesized by high temperature solid state reaction in air. The crystal structureswere determined from power X-ray diffraction(XRD), which all crystallize in the monoclinic space group P21/c. Sr4GaTaO8 is isostructural to the previous reported Sr4AlNbO8, whichin fact is a B-site ordered and oxygen-deficient triple perovskite
