2.3.1.286 metabolism Sir2 is involved in the regulation of p53 function via deacetylation 729560 2.3.1.286 metabolism SIRT1 modulates DNA repair activity, which can be regulated by the acetylation status of repair protein Ku70 following DNA damage 729683 2.3.1.286 metabolism the deacetylation of [histone H4]-N6-acetyl-L-lysine16 by Sirt2 may be pivotal to the formation of condensed chromatin 729802 2.3.1.286 metabolism acetylation of Lys413 decreases catalysis and SIRT3 reactivates isocitrate dehydrogenase 2 upon deacetylation. SIRT3-dependent deacetylation of isocitrate dehydrogenase 2 suppresses cellular stress by reactive oxygen species (ROS). Acetylation of Lys413 is regulated by SIRT3 in response to calorie and glucose restriction 729982 2.3.1.286 metabolism the enzyme can regulate flux and anapleurosis of this central metabolic cycle 730205 2.3.1.286 metabolism caloric restriction can extend life-span by inducing SIRT1 expression and promoting the long-term survival of irreplaceable cells 730962 2.3.1.286 physiological function enzyme expression is crucial for the survival of the cell 737969 2.3.1.286 malfunction SIRT1 depletion by RNA interference attenuates capsaicin-induced apoptosis in A-549 cancer cells and autophagy in MRC-5 cells 738438 2.3.1.286 metabolism isoform SIRT3 levels modulate mitochondrial protein folding 738661 2.3.1.286 physiological function acetylation of heat shock protein 10 by isoform SIRT3 enhances medium-chain acyl-CoA dehydrogenase folding, enzyme activity, and fat oxidation 738661
