Methyl and acetyl groupes can be added to the tails of histones.
举一反三
- In order to package the 3x109 nucleotides of DNA into the nucleus, the DNA is wound around histones. These are proteins that bind to the DNA. The interaction of histones and DNA involves:
- Removal of which following group produces more active deadenylylated glutamine synthetase, and glutamine is formed？ A: acetyl B: phosphoryl C: methyl D: adenylyl
- Histone deacetylases (HDACs) are a group of enzymes closely related to __________. They catalyze acetyl group removal from lysine residues in histones and non-histone proteins, causing transcriptional repression. HDACs are usually components of multiprotein complexes.
- Which is the following can transfer acetyl group from mitochondria to cytoplasm
- Acetyl CoA can be finally oxidized to CO2 and H2O via citric acid cycle.
