Acetyltransferases

Acetyltransferases are enzymes that help modify other molecules by adding an acetyl group—a small chemical fragment—to them. This process, called acetylation, can change how proteins or other molecules behave, influencing their activity, stability, or location within the cell. These enzymes are essential for regulating many biological functions, such as gene expression, metabolism, and protein interactions. By selectively attaching acetyl groups, acetyltransferases play a key role in maintaining healthy cell operations and are involved in various processes, including aging, immune response, and disease development.
