CC -!- FUNCTION: NAD-dependent protein deacetylase which modulates the
CC activities of several enzymes which are inactive in their acetylated
CC form. Deacetylates the N-terminal lysine residue of Alba, the major
CC archaeal chromatin protein and that, in turn, increases Alba's DNA
CC binding affinity, thereby repressing transcription. {ECO:0000255|HAMAP-
CC Rule:MF_01968}.
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 EC=2.3.1.286; Evidence={ECO:0000255|HAMAP-Rule:MF_01968};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01968};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01968};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01968}.
CC -!- SIMILARITY: Belongs to the sirtuin family. Class U subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_01968}.
