CC -!- FUNCTION: NAD-dependent lysine deacetylase and desuccinylase that
CC specifically removes acetyl and succinyl groups on target proteins.
CC Modulates the activities of several proteins which are inactive in
CC their acylated form. {ECO:0000256|HAMAP-Rule:MF_01121}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(6)-acetyl-L-lysyl-[protein] + NAD(+) = 2''-O-acetyl-
CC ADP-D-ribose + L-lysyl-[protein] + nicotinamide;
CC Xref=Rhea:RHEA:43636, Rhea:RHEA-COMP:9752, Rhea:RHEA-COMP:10731,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:17154, ChEBI:CHEBI:29969,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:61930, ChEBI:CHEBI:83767;
CC EC=2.3.1.286; Evidence={ECO:0000256|HAMAP-Rule:MF_01121};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(6)-succinyl-L-lysyl-[protein] + NAD(+) = 2''-O-
CC succinyl-ADP-D-ribose + L-lysyl-[protein] + nicotinamide;
CC Xref=Rhea:RHEA:47668, Rhea:RHEA-COMP:9752, Rhea:RHEA-COMP:11877,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:17154, ChEBI:CHEBI:29969,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:87830, ChEBI:CHEBI:87832;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01121};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01121};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_01121};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01121}.
CC -!- DOMAIN: 2 residues (Tyr-57 and Arg-60) present in a large hydrophobic
CC pocket are probably involved in substrate specificity. They are
CC important for desuccinylation activity, but dispensable for
CC deacetylation activity. {ECO:0000256|HAMAP-Rule:MF_01121}.
CC -!- SIMILARITY: Belongs to the sirtuin family. Class III subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01121}.
