Comments [?]

Function Endoribonuclease that plays a central role in RNA processing and decay. Required for the maturation of 5S and 16S rRNAs and the majority of tRNAs. Also involved in the degradation of most mRNAs.
Catalytic activity Reaction=Endonucleolytic cleavage of single-stranded RNA in A- and U-rich regions.; EC=;
case <FTGroup:2>
Cofactor Zn(2+)
Note: Binds 2 Zn(2+) ions per homotetramer.
end case
case <FTGroup:1>
Cofactor Mg(2+)
Note: Binds 1 Mg(2+) ion per subunit.
end case
case <OC:Gammaproteobacteria>
Subunit Component of the RNA degradosome, which is a multiprotein complex involved in RNA processing and mRNA degradation. Within the RNA degradosome, RNase E assembles into a homotetramer formed by a dimer of dimers.
Subunit Homotetramer formed by a dimer of dimers.
end case
Subcellular location Cytoplasm. Cell inner membrane; Peripheral membrane protein; Cytoplasmic side.
Similarity Belongs to the RNase E/G family. RNase E subfamily.
