What is the Origin of Histone Deacetylases?

The term combines "histone," the core protein of the nucleosome, and "deacetylase," the enzyme class that performs the removal of the acetyl group. The discovery of HDACs and their counteracting enzymes, histone acetyltransferases, revealed a major mechanism for regulating gene accessibility. This concept is central to the field of epigenetics, which studies heritable changes in gene function that do not involve alterations to the DNA sequence.

What is the Mechanism of Histone Deacetylases?

The core enzymatic mechanism involves the removal of the negatively charged acetyl group, which restores the positive charge on the histone's lysine residue. This restoration increases the electrostatic attraction between the histones and the negatively charged DNA backbone, causing the chromatin to condense. This physical compaction restricts the access of the transcriptional machinery to the gene promoter, effectively turning off gene transcription in a process often recruited by nuclear hormone receptor complexes.

Histone Deacetylases

Meaning

Histone deacetylases (HDACs) are a family of enzymes that catalyze the removal of acetyl groups from the lysine residues on histone proteins, the structural spools around which DNA is tightly wrapped. This enzymatic activity promotes a more compact, condensed chromatin structure, which typically results in the transcriptional repression or silencing of the associated genes. HDACs are critical epigenetic regulators that link cellular signaling to genetic expression.
