Histone Deacetylase 8 (HDAC 8)

Introduction

Histone deacetylase 8 (HDAC 8) is an enzyme that plays a role in controlling gene expression. Specifically, it catalyzes the removal of an acetyl group off of the ε-amino-lysine sidechain of N-terminal core of Histone proteins. By removing the acetate ion, the reclaimed positive charge on the lysine sidechain is able to interact with the negative charge on the DNA. As a result, DNA will bind more tightly to the histone protein reducing transcription and expression.

Instead of the Asp-His-Ser, HDAC8 uses the His to coordinate a H2O nucleophile.
