CC -!- FUNCTION: NAD-dependent lysine deacetylase that specifically removes
CC acetyl groups on target proteins. Also acts as a protein-lysine
CC deacylase by mediating protein desuccinylation and de-2-
CC hydroxyisobutyrylation. Modulates the activities of several proteins
CC which are inactive in their acylated form. {ECO:0000256|HAMAP-
CC Rule:MF_01121}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N(6)-(2-hydroxyisobutanoyl)-L-lysyl-[protein] + NAD(+) =
CC 2''-O-(2-hydroxyisobutanoyl)-ADP-D-ribose + L-lysyl-[protein] +
CC nicotinamide; Xref=Rhea:RHEA:24364, Rhea:RHEA-COMP:9752, Rhea:RHEA-

CC -!- CATALYTIC ACTIVITY:

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

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-94 and Arg-97) 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}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01121,
CC ECO:0000256|PROSITE-ProRule:PRU00236}.
