CC -!- FUNCTION: NAD-dependent lysine demalonylase, desuccinylase and
CC deglutarylase that specifically removes malonyl, succinyl and glutaryl
CC groups on target proteins. Has weak NAD-dependent protein deacetylase
CC activity; however this activity may not be physiologically relevant in
CC vivo. {ECO:0000255|HAMAP-Rule:MF_03160}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(6)-malonyl-L-lysyl-[protein] + NAD(+) = 2''-O-malonyl-
CC ADP-D-ribose + L-lysyl-[protein] + nicotinamide;

CC glutaryl-ADP-D-ribose + L-lysyl-[protein] + nicotinamide;

CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03160};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_03160};
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000255|HAMAP-Rule:MF_03160,
CC ECO:0000269|PubMed:17214740}.
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-57 and
CC Arg-60) that bind to malonylated and succinylated substrates and define
CC the specificity. {ECO:0000255|HAMAP-Rule:MF_03160}.
CC -!- MISCELLANEOUS: This protein may be expected to contain an N-terminal
CC transit peptide but none has been predicted. {ECO:0000255|HAMAP-
CC Rule:MF_03160}.
CC -!- SIMILARITY: Belongs to the sirtuin family. Class III subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_03160}.
