Sirtuin. Sirtuins are a family of signaling proteins involved in metabolic regulation. [ 2][ 3] They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. [ 2] Chemically, sirtuins are a class of proteins that possess either mono- ADP-ribosyltransferase or deacylase activity ...
Sirtuin-activating compound. Sirtuin-activating compounds ( STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases. [ 1]
Sirtuin 6. Sirtuin 6 ( SIRT6 or Sirt6) is a stress responsive protein deacetylase and mono-ADP ribosyltransferase enzyme encoded by the SIRT6 gene. [ 5][ 6][ 7] In laboratory research, SIRT6 appears to function in multiple molecular pathways related to aging, including DNA repair, telomere maintenance, glycolysis and inflammation. [ 5]
Sirtuin 3. NAD-dependent deacetylase sirtuin-3, mitochondrial also known as SIRT3 is a protein that in humans is encoded by the SIRT3 gene [sirtuin (silent mating type information regulation 2 homolog) 3 (S. cerevisiae)]. [ 5][ 6] SIRT3 is member of the mammalian sirtuin family of proteins, which are homologs to the yeast Sir2 protein.

Sirtuin 2. NAD-dependent deacetylase sirtuin 2 is an enzyme that in humans is encoded by the SIRT2 gene. [5] [6] [7] SIRT2 is an NAD+ (nicotinamide adenine dinucleotide)-dependent deacetylase. Studies of this protein have often been divergent, highlighting the dependence of pleiotropic effects of SIRT2 on cellular context.
