WebNov 3, 2016 · To find out who’s sitting at the sirtuins’ table, the scientists created a map of protein interactions—the interactome—of sirtuins found in mitochondria, the cell’s source of energy. They then used that map to reveal how one particular sirtuin works with its protein partners to keep the cell’s powerhouse humming. Get more HMS news here. WebSirtuins are evolutionary conserved, NAD +-dependent protein lysine deacylases regulating functions such as energy metabolism and stress responses. They have been …

SIRTfoods diet: Sirtuins and turning on your skinny genes

Unlike other known protein deacetylases, which simply hydrolyze acetyl-lysine residues, the sirtuin-mediated deacetylation reaction couples lysine deacetylation to NAD+ hydrolysis. This hydrolysis yields O-acetyl-ADP- ribose , the deacetylated substrate and nicotinamide , which is an inhibitor of sirtuin activity … See more Sirtuins are a family of signaling proteins involved in metabolic regulation. They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. Chemically, sirtuins are a class … See more Sirtuins are a family of signaling proteins involved in metabolic regulation.
