" /> sirtuins - CISMeF





Preferred Label : sirtuins;

MeSH definition : A homologous family of regulatory enzymes that are structurally related to the protein silent mating type information regulator 2 (Sir2) found in Saccharomyces cerevisiae. Sirtuins contain a central catalytic core region which binds NAD. Several of the sirtuins utilize NAD to deacetylate proteins such as HISTONES and are categorized as GROUP III HISTONE DEACETYLASES. Several other sirtuin members utilize NAD to transfer ADP-RIBOSE to proteins and are categorized as MONO ADP-RIBOSE TRANSFERASES, while a third group of sirtuins appears to have both deacetylase and ADP ribose transferase activities.;

MeSH synonym : silent mating type information regulator 2 like proteins; sir2-like proteins; silent mating type information regulator 2-like proteins; sir2 like proteins; SIRTs; SIRT; Sirtuin;

CISMeF synonym : deacetylases, nad-dependent protein; nad-dependent protein deacetylases; nad dependent protein deacetylases; protein deacetylases, nad-dependent;

Registry Number MeSH : EC 3.5.1.-;
