The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

CONTINUING THE DEVELOPMENT OF A 100 FEMTOSECOND X-RAY DETECTOR [PDF]
The detector is an x-ray streak camera running in accumulation mode for time resolved x-ray studies at the existing third generation synchrotron facilities and will also be used for the development and applications of the fourth generation x-ray sources.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Ultrafast X-Ray Detector and its Gain Uniformity
An ultrafast x-ray detector consisted of an electron pulse time-dilation device, a combined electromagnetic lens system, a microchannel plate (MCP) gated imager, and an electrical pulse generator is reported.

Hard X-ray scanning transmission microscopy with a 2D pixel array detector [PDF]
X-ray microscopy is an invaluable tool for the characterization of life and materials science samples on the submicron length scale. Particularly in case of hard X-rays, it combines high penetration power with elemental, chemical, and magnetic ...

In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

MOS CCDs for the wide field imager on the XEUS spacecraft [PDF]
In recent years the XEUS mission concept has evolved and has been the subject of several industrial studies. The mission concept has now matured to the point that it could be proposed for a Phase A study and subsequent flight programme.
