WebHistone-modifying enzymes are enzymes involved in the modification of histone substrates after protein translation and affect cellular processes including gene expression. [1] [2] To safely store the eukaryotic genome, DNA is wrapped around four core histone proteins (H3, H4, H2A, H2B), which then join to form nucleosomes. WebIn 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 …
