[[http://www.uniprot.org/uniprot/SIR3_HUMAN SIR3_HUMAN]] NAD-dependent protein deacetylase. Activates mitochondrial target proteins, including ACSS1, IDH2 and GDH by deacetylating key lysine residues. Contributes to the regulation of the cellular energy metabolism. Important for regulating tissue-specific ATP levels.<ref>PMID:16788062</ref> <ref>PMID:18680753</ref> <ref>PMID:18794531</ref> <ref>PMID:19535340</ref> [[http://www.uniprot.org/uniprot/ACS2L_HUMAN ACS2L_HUMAN]] Important for maintaining normal body temperature during fasting and for energy homeostasis. Essential for energy expenditure under ketogenic conditions (By similarity). Converts acetate to acetyl-CoA so that it can be used for oxidation through the tricarboxylic cycle to produce ATP and CO(2).<ref>PMID:16788062</ref>
