WebAug 15, 2024 · DNA wraps around proteins called histones. When histones are tightly packed together, proteins that ‘read’ the gene cannot access the DNA as easily, so the gene is turned “off.” When histones are loosely packed, more DNA is exposed or not wrapped around a histone and can be accessed by proteins that ‘read’ the gene, so the gene is … WebTo allow for chromatin targeting and remodeling, all SWI/SNF components comprise protein-protein or DNA-binding domains, which facilitate the displacement of DNA in an ATP-dependent manner. In binding to the nucleosome, nucleosome-remodeling complexes use energy harvested from ATP hydrolysis to remodel chromatin structure [76].
WebFurthermore, the details of protein-protein and protein-DNA interactions were fine-tuned by X-ray crystallography studies at 2.8 and 1.9 Å, respectively, in the 2000s. ...

WebProteins bind to DNA through the same forces that hold strands of DNA together, namely H-bonds and ionic interactions. Different amino acids contain H-bond donors and acceptors, and charged residues on their side chains. DNA binding proteins tend to bind in the major groove of DNA for two reasons.
