Lysine deacetylation

Lysine deacetylation is a biological process where an enzyme called a deacetylase removes an acetyl group from a lysine amino acid in a protein. This modification influences the protein's activity, stability, and interaction with other molecules, often affecting gene expression and cell function. Essentially, deacetylation acts as a regulatory switch that can turn certain proteins on or off. It plays a vital role in many processes, including gene regulation, cell growth, and response to stress, making it an important area of study in health and disease.
