Crystallographic refinement of ricin to 2.5 a

WebThe crystal structure of a complex containing the DNA-binding domain of lambda repressor and a lambda operator site was determined at 2.5 Å resolution and refined to a crystallographic R factor of 24.2 percent. The complex is stabilized by an extensive network of hydrogen bonds between the protein and the sugar-phosphate backbone. WebApr 12, 2024 · When Sc content is increased beyond the eutectic point, grain size decreases more significantly. An addition of 0.7 wt.% Sc can refine the grain to 40 μm. Figure 3 b shows that the grain size is fine and uniform, and the reduction rate reaches 95.3%. This difference in refinement results from refinement mechanism.
