Structural Dynamics

The November 2024 issue of Structural Dynamics features an exciting article titled "ProteinReDiff: Complex-based ligand-binding proteins redesign by equivariant diffusion-based generative models." This article introduces ProteinReDiff, a method that integrates refined diffraction data with computational modeling to study ligand binding in proteins. The approach provides high-resolution insights into binding sites, affinities, and conformational changes, advancing our understanding of protein-ligand interactions. This innovative tool holds significant potential for drug discovery and protein engineering, enabling the design of more effective ligands and inhibitors. [Read the full article here.]

Snowflakes are a captivating example of crystallography in nature, showcasing the intricate beauty of ice crystals formed through precise molecular arrangements. Each snowflake begins with a tiny ice nucleus, often a single water molecule that freezes and grows symmetrically as additional water vapor condenses onto it. The hexagonal structure of snowflakes arises from the molecular geometry of water, where hydrogen bonds form a six-fold symmetry. Crystallographers study these patterns to understand the physics of crystal growth and the environmental conditions influencing snowflake formation. The study of snowflakes not only reveals insights into natural processes but also exemplifies how crystallography underpins our understanding of symmetry, geometry, and molecular interactions in the world around us.
