Description
Sirtuins, which are NAD-dependent lysine deacetylases, have been implicated in the control of longevity in yeast and C. elegans and, in yeast, have been shown to be necessary for the longevity increase effected by caloric restriction. Human SIRT3, one of seven human sirtuins, has been assigned, along with SIRT1 and SIRT2, to the class I sirtuin homology group
