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. 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 1 is a member of the sirtuin family of proteins, homologs of the Sir2 gene in S. cerevisiae. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing ...

Sirtuin (silent mating type information regulation 2 homolog) 5 (S. cerevisiae), also known as SIRT5 is a protein which in humans in encoded by the SIRT5 gene and in other species by the orthologous Sirt5 gene. [5] This gene encodes a member of the sirtuin family of proteins, 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.
