Abstract:
Our current level of understanding of chromatin structure was to a large extent achieved with the help of DNA-protein cross-linking. The versatile inventory of cross-linking techniques allows the identification of the contacts between DNA and proteins with a single nucleotide-single amino acid precision, to detect minor components of the complex nucleoprotein systems, to reveal the interactions of the flexible protein domains with DNA, and to assay for conformational changes in the nucleosomes.
