    SUBCELLULAR LOCALIZATION     intracellular
    text can indeed be translocated into the mitochondrial intermembrane space, but also into the matrix (localization might contribute to SIRT5 regulation and substrate selection) (Schlicker 2008)
    basic FUNCTION
  • NAD(+) ADP ribosyltransferase with a protein deacetylase activity
  • can deacetylate and thereby activate a central metabolic regulator in the mitochondrial matrix, glutamate dehydrogenase (Schlicker 2008)
  • can deacetylate cytochrome c, a protein of the mitochondrial intermembrane space with a central function in oxidative metabolism, as well as apoptosis initiation (Schlicker 2008)
  • by participating in the stress response to genomic insults, sirtuins are thought to protect against cancer, but they are also emerging as direct participants in the growth of some cancers (Saunders 2007)
  • plays a pivotal role in ammonia detoxification and disposal by activating CPS1 (Nakagawa 2009)
  • CELLULAR PROCESS nucleotide, transcription, regulation
