Deacetylation (pronounced: dee-uh-set-l-ay-shun) is a biochemical process that involves the removal of an acetyl group from a molecule. The opposite process, which involves the addition of an acetyl group, is known as acetylation.

Etymology

The term "deacetylation" is derived from the prefix "de-", which means "removal" or "reversal", and "acetylation", which refers to the process of introducing an acetyl group into a molecule.

Process

Deacetylation is a key process in cellular functions and is carried out by enzymes known as deacetylases. These enzymes remove acetyl groups from proteins, particularly from histones, which are proteins that help package DNA in the nucleus of a cell. This process is crucial for the regulation of gene expression, as it can affect how genes are turned on or off.
