Cysteine cross linking
WebJul 23, 2024 · Cysteine (Cys) is a crucial thiol-containing amino acid which plays a critical role in human pathologies [1,2], and is found in huge quantities in protein-rich foods [].In animal cells, Cys participates in many important and essential biological functions, including protein synthesis, detoxification, and metabolism [].Normally, the concentrations of Cys … WebCovalent protein capture (cross-linking) by reactive DNA derivatives makes it possible to investigate structural features by fixing complexes at different stages of DNA–protein recognition. The most common cross-linking methods are based on reactive groups that interact with native or engineered cysteine residues.
