CC   -!- FUNCTION: NAD-dependent protein deacetylase which modulates the
CC       activities of several enzymes which are inactive in their acetylated
CC       form. {ECO:0000255|HAMAP-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;
