WebJan 31, 2024 · What Is Protein Crystallography? We use protein crystallography to determine, experimentally, the structure of proteins. The method applies to other macromolecules, such as nucleic acid and … WebOften proteins may be stabilized when they are complexed with a substrate, nucleic acid, cofactor or small molecule. These ligands, on the other hand, have the potential to induce significant conformational changes to the protein and ab initio screening may be required to find a new crystal form. This paper presents an overview of strategies in ...
