CC -!- FUNCTION: NAD-dependent lysine demalonylase, desuccinylase and
CC deglutarylase that specifically removes malonyl, succinyl and glutaryl
CC groups on target proteins. Activates CPS1 and contributes to the
CC regulation of blood ammonia levels during prolonged fasting: acts by
CC mediating desuccinylation and deglutarylation of CPS1, thereby
CC increasing CPS1 activity in response to elevated NAD levels during
CC fasting. Activates SOD1 by mediating its desuccinylation, leading to
CC reduced reactive oxygen species. Activates SHMT2 by mediating its
CC desuccinylation. Modulates ketogenesis through the desuccinylation and
CC activation of HMGCS2. Has weak NAD-dependent protein deacetylase
CC activity; however this activity may not be physiologically relevant in
CC vivo. Can deacetylate cytochrome c (CYCS) and a number of other
CC proteins in vitro such as UOX. {ECO:0000255|HAMAP-Rule:MF_03160}.

CC {ECO:0000255|HAMAP-Rule:MF_03160}. Note=Mainly mitochondrial. Also
CC present extramitochondrially, with a fraction present in the cytosol
CC and very small amounts also detected in the nucleus.
CC {ECO:0000255|HAMAP-Rule:MF_03160}.
CC -!- ALTERNATIVE PRODUCTS:

CC IsoId=Q5R6G3-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q5R6G3-2; Sequence=VSP_021600;
CC -!- DOMAIN: In contrast to class I sirtuins, class III sirtuins have only
CC weak deacetylase activity. Difference in substrate specificity is
CC probably due to a larger hydrophobic pocket with 2 residues (Tyr-102
CC and Arg-105) that bind to malonylated and succinylated substrates and
CC define the specificity. {ECO:0000255|HAMAP-Rule:MF_03160}.
CC -!- SIMILARITY: Belongs to the sirtuin family. Class III subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_03160}.
