CC -!- FUNCTION: NAD-dependent protein deacylase. Catalyzes the NAD-dependent
CC hydrolysis of acyl groups from lysine residues. Plays a role in
CC oxidative stress resistance (PubMed:23438705). {ECO:0000255|HAMAP-
CC Rule:MF_03161, ECO:0000269|PubMed:23438705}.
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 -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03161};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_03161};
CC -!- SUBUNIT: Interacts with pyc-1, pcca-1 and mccc-1.
CC {ECO:0000269|PubMed:23438705}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000255|HAMAP-
CC Rule:MF_03161}. Mitochondrion {ECO:0000269|PubMed:23438705}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=a;
CC IsoId=Q20480-1; Sequence=Displayed;
CC Name=b;
CC IsoId=Q20480-2; Sequence=VSP_043534;
CC Name=c;
CC IsoId=Q20480-3; Sequence=VSP_043533, VSP_043534;
CC -!- TISSUE SPECIFICITY: Ubiquitously expressed with high expression in the
CC pharynx, body wall muscles and gonad. {ECO:0000269|PubMed:23438705}.
CC -!- DEVELOPMENTAL STAGE: Expression is first detected at the three-fold
CC stage during embryogenesis. {ECO:0000269|PubMed:23438705}.
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_03161}.
CC -!- SIMILARITY: Belongs to the sirtuin family. Class II subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_03161}.
