WebJul 5, 2006 · The ability of sirtuins to deacetylate and activate acetylated AceCS2 was followed by measuring the rate acetyl-CoA formation (nmol of acetyl-CoA per min per mg of protein). (D) Acetylation state of AceCS2 can be detected with an anti-acetyl-AceCS antibody. Recombinant AceCS2 and acetyl-AceCS2 were resolved by SDS/PAGE and … WebSirtuins deacetylate a variety of substrates such as transcription factors, enzymes, and histones. They control diverse biological processes including metabolism, cell growth, aging apoptosis, and autophagy . In the present review we focus on the role of non-mitochondrial SIRT1, SIRT2, and SIRT6 in the brain damage and recovery after ischemic ...
Histone deacetylases (EC 3.5.1.98, HDAC) are a class of enzymes that remove acetyl groups (O=C-CH3) from an ε-N-acetyl lysine amino acid on both histone and non-histone proteins. HDACs allow histones to wrap the DNA more tightly. This is important because DNA is wrapped around histones, and DNA expression is regulated by acetylation and de-acetylation. HDAC's action is opposite to that of histone … WebJul 19, 2016 · Deacetylase inhibition promotes the generation and function of…
WebMay 20, 2004 · Members of the class I histone deacetylases (HDAC) regulate the transcriptional activity of NF-κB. HDAC1, HDAC2, and HDAC3 deacetylate RelA/p65, resulting in increased IκBα association or loss of transactivation potential of the protein (Ashburner et al, 2001; Chen et al, 2001; Zhong et al, 2002).
