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:0000255|HAMAP-
CC 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 Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01121};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01121}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative promoter usage; Named isoforms=2;
CC Name=CobB-Long {ECO:0000250|UniProtKB:P0A2F2};
CC IsoId=Q8FIM4-1; Sequence=Displayed;
CC Name=CobB-Short {ECO:0000250|UniProtKB:P0A2F2};
CC IsoId=Q8FIM4-2; Sequence=VSP_058460;
CC -!- DOMAIN: 2 residues (Tyr-92 and Arg-95) 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:0000255|HAMAP-Rule:MF_01121}.
CC -!- SIMILARITY: Belongs to the sirtuin family. Class III subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01121}.
