CC -!- FUNCTION: Endoribonuclease that plays a central role in RNA processing
CC and decay. Required for the maturation of 5S and 16S rRNAs and the
CC majority of tRNAs. Also involved in the degradation of most mRNAs.
CC {ECO:0000256|HAMAP-Rule:MF_00970}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endonucleolytic cleavage of single-stranded RNA in A- and U-
CC rich regions.; EC=3.1.26.12; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00970};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00970};
CC Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00970};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00970};
CC Note=Binds 2 Zn(2+) ions per homotetramer. {ECO:0000256|HAMAP-
CC Rule:MF_00970};
CC -!- SUBUNIT: Homotetramer formed by a dimer of dimers. {ECO:0000256|HAMAP-
CC Rule:MF_00970}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00970}. Cell
CC inner membrane {ECO:0000256|HAMAP-Rule:MF_00970}; Peripheral membrane
CC protein {ECO:0000256|HAMAP-Rule:MF_00970}; Cytoplasmic side
CC {ECO:0000256|HAMAP-Rule:MF_00970}.
CC -!- SIMILARITY: Belongs to the RNase E/G family. RNase E subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_00970}.
