Recombinant Human SIRT3

Cat. No.: SIRT3-341H
Description: Sirtuins are pylogenetically conserved from bacteria to humans and regulate cell functions beyond silencing. The proteins show a relevance to cancer, obesity, muscle differentiation, inflammation and neuro-degeneration. In addition, Sirtuin activity may extend the lifespan of several organisms. Human Sirtuin 3 (Sirt3) is a mitochondrial member of Class III of the protein deacetylases family (historically called histone deacetylases family). Class III deacetylases utilize NAD+ as cosubstrate and act either as deacetylases or as ADP-ribosyltransferases. Sirt3 regulates mitochondrial function and thermogenesis; the enzyme can deacetylate and thereby activate the mitochondrial acetyl-CoA synthetase 2 which enables mitochondria to activate acetate for metabolic reactions. MW=32.2kDa (292 amino acids).
Source: E.coli.
