How to crystallize a protein

WebThere are two main techniques for solving protein structures: x-ray crystallography and Nuclear Magnetic Resonance (NMR). As can be seen from the current PDB holdings, more than 77,000 protein structures have been solved so far, and are available from the Protein Data Bank. What is crystal structure? WebBeyond that all requirements for the protein solution itself remain valid as described in [1] in more detail. 2. Binding protein with one ligand – How to crystallize and what can be deduced from the structure A typical class of a protein binding one ligand are substrate-binding proteins (SBPs), and substrate-binding domains (SBDs) [2].
