Comment typeDescription
Catalytic ActivityNAD(+) + an acetylprotein = nicotinamide + O- acetyl-ADP-ribose + a protein. {ECO:0000255|PROSITE- ProRule:PRU00236}.
CofactorName=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250}; Note=Binds 1 zinc ion per subunit. {ECO:0000250};
FunctionNAD-dependent histone deacetylase, which contributes together with HST4 to histone H3 'Lys-56' deacetylation, regulation of telomeric silencing, proper cell cycle progression, DNA damage control, DNA recombination, and genomic maintenance. {ECO:0000269|PubMed:10841563, ECO:0000269|PubMed:16487579, ECO:0000269|PubMed:16815704, ECO:0000269|PubMed:17106263}.
