CC   -!- FUNCTION: Deacetylates O-acetyl-ADP ribose to yield ADP-ribose and free
CC       acetate. Down-regulates ribonuclease 3 (RNase III) activity. Acts by
CC       interacting directly with the region of the ribonuclease that is
CC       required for dimerization/activation. {ECO:0000255|HAMAP-
CC       Rule:MF_01205}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=3''-O-acetyl-ADP-D-ribose + H2O = acetate + ADP-D-ribose +
CC         H(+); Xref=Rhea:RHEA:59244, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:30089, ChEBI:CHEBI:57967, ChEBI:CHEBI:142723;

CC         EC=3.1.1.106; Evidence={ECO:0000255|HAMAP-Rule:MF_01205};
CC   -!- SUBUNIT: Homodimer. Interacts with RNase III. {ECO:0000255|HAMAP-
CC       Rule:MF_01205}.
CC   -!- SIMILARITY: Belongs to the YmdB family. {ECO:0000255|HAMAP-
CC       Rule:MF_01205, ECO:0000305}.
