  • Highlights? CBC binds to the minor groove of the DNA and bends it in a nucleosome-like manner ? Interactions of subunit HapB with DNA explain the sequence specificity of the CBC ? Anchor A of HapB tethers the CBC to the CCAAT box by minor groove widening ? Interactions of the CBC with the histones H3/H4 of the nucleosome are modeled
