August undefined, 2024

WebHistone acetylation is mediated by acetyl-coenzyme A, and in histone deacetylation the acetyl group is transferred to coenzyme A. Histone acetylation is catalyzed by histone acetyltransferases (HATs), while histone deacetylation is catalyzed by histone deacetylases (denoted by HDs or HDACs). WebHistone acetyla-tion and deacetylation are modulated by the interplay between HATs and HDACs, which results in modifica-tions to chromatin structure and regulation of transcrip …
