Currently, over 500 ...Nucleosomes are fundamental elements of chromatin organization that participate in compacting genomic DNA and serve as targets for the binding of numerous regulatory proteins. Currently, over 500 different nucleosome structures are known. Despite the large number of nucleosome structures, all of them were formed on only about twenty different DNA sequences. Using cryo-electron microscopy, we determined the structure of the nucleosome formed on a high-affinity Widom 603 DNA sequence at 4 Å resolution; an atomic model was built. We proposed an integrative modeling approach to study the nucleosomal DNA unwrapping based on the cryoelectron microscopy (cryo-EM) data. We also demonstrated the DNA unwrapping of the Widom 603 nucleosome using small angle X-ray scattering and single particle Förster resonance energy transfer measurements. Our results are consistent with the asymmetry of nucleosomal DNA unwrapping. Our data revealed the dependence of nucleosome structure and dynamics on the sequence of nucleosomal DNA. | ||||||

Prior ...詳細: The DNA chains of the initial model (7VZ4) were replaced with mutate_bases tool of 3DNA v2.1 by only swapping the bases itself, while preserving the sugar-phosphate backbone geometry. Prior to refinements, the set of adaptive restraints for the protein chains (distances and dihedral angles) was created in ISOLDE based on the initial model (7VZ4), along with hydrogen bond restraints for the DNA. ISOLDE refinement was followed by the PHENIX real space refinement, with the protein chains restrained to themselves and the DNA restrained with base-pair hydrogen bonds and planarity.
