Histone octamer assembly
The histone octamer interacts with the DNA through both its core histone folds and N-terminal tails. The histone fold interacts chemically and physically with the DNA's minor groove . Studies have found that the histones interact more favorably with A : T enriched regions than G : C enriched regions in the … Visa mer In molecular biology, a histone octamer is the eight-protein complex found at the center of a nucleosome core particle. It consists of two copies of each of the four core histone proteins (H2A, H2B, H3, and H4). The octamer … Visa mer Core histones are four proteins called H2A, H2B, H3 and H4 and they are all found in equal parts in the cell.
