C [auth B]PF00850Histone deacetylase domain (Hist_deacetyl)Histone deacetylase domainHistones can be reversibly acetylated on several lysine residues. Regulation of transcription is caused in part by this mechanism. Histone deacetylases catalyse the removal of the acetyl group. Histone deacetylases are related to other proteins [1]. ...Histones can be reversibly acetylated on several lysine residues. Regulation of transcription is caused in part by this mechanism.
