WebApr 24, 2024 · Introduction. Reversible histone acetylation and deacetylation functions play a key role in gene regulation. The process of acetylation and deacetylation are accelerated by enzymes Histone acetyl transferases (HATs) and Histone deacetylases (HDACs), respectively (Icardi et al., 2012; Rousseaux and Khochbin, 2015).Small molecule …
WebJul 5, 2006 · A Sir2 homologue in Salmonella enterica was shown to regulate the activity of AceCS through deacetylation, permitting bacterial growth on acetate and propionate ().These observations led to our hypothesis that mammalian sirtuins might control acetyl-CoA synthetases and modulate acetyl-CoA synthesis from acetate. WebHATs and HDACs are recruited to DNA by association with transcription factors (TFs). Acetylation of histone tails results in chromatin relaxation and gene activation. Deacetylation opposes transcriptional activation by promoting chromatin condensation. In addition to their roles as transcriptional activators and repressors, HATs and HDACs …

WebHistone acetylation is an important regulatory mechanism that controls transcription and diverse nuclear processes. While great progress has been made in understanding how localized acetylation and deacetylation control promoter activity, virtually nothing is known about the consequences of acetylation throughout entire chromosomal regions.
WebHistone acetylation and histone deacetylation play key roles in the epigenetic regulation.
