X-Ray Crystallography

With the aid of highly advanced microscopes and synchrotron sources, researchers from the University of Copenhagen have gained seminal insight into how bacteria function as defence mechanisms against attacks from other bacteria and viruses. The study, which has just been published in the journal, Na more

by Xuekui Yu, Lei Jin, Jonathan Jih, Chiaho Shih, Z. Hong Zhou The capsid shell of infectious hepatitis B virus (HBV) is composed of 240 copies of a single protein called HBV core antigen (HBc). An atomic model of a core assembled from truncated HBc was determined previously by X-ray crystall more

Despite the prominent role of horizontal gene transfer (HGT) in shaping bacterial metabolism, little is known about the impact of HGT on the evolution of enzyme function. Specifically, what is the influence of a recently acquired gene on the function of an existing gene? For example, certain member more

Abstract Protein‐DNA interactions are essential for many biological processes, X‐ray crystallography can provide high‐resolution structures, but protein‐DNA complexes are difficult to crystallize and typically contain only small DNA fragments. Thus, there is a need for computational methods that more
