CC   -!- FUNCTION: An RNase that has 5'-3' exonuclease and possibly
CC       endoonuclease activity. Involved in maturation of rRNA and in some
CC       organisms also mRNA maturation and/or decay (By similarity).
CC       {ECO:0000250}.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01491};
CC       Note=Binds up to 2 Zn(2+) ions per subunit. It is not clear if Zn(2+)
CC       or Mg(2+) is physiologically important. {ECO:0000255|HAMAP-
CC       Rule:MF_01491};
CC   -!- SUBUNIT: Homodimer, may be a subunit of the RNA degradosome.
CC       {ECO:0000255|HAMAP-Rule:MF_01491}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01491}.
CC   -!- SIMILARITY: Belongs to the metallo-beta-lactamase superfamily. RNA-
CC       metabolizing metallo-beta-lactamase-like family. Bacterial RNase J
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01491}.
