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. Web1. Genetic regulatory proteins bind to the DNA 2. A transcription terminator forms in the RNA 3. Repressor proteins bind to an mRNA and prevent ribosome binding 4. Riboswitches produce an RNA conformation that prevents ribosome binding 5. Antisense RNA binds to the mRNA 6. The product of a metabolic pathway inhibits the first enzyme in a pathway 7.

WebThese modifications include phosphorylation, glycosylation, ubiquitination, nitrosylation, methylation, acetylation, lipidation and proteolysis and influence almost all aspects of normal cell biology and pathogenesis.
