Function

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.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

  • Endonucleolytic cleavage of single-stranded RNA in A- and U-rich regions.
    EC:3.1.26.12 (UniProtKB | ENZYME | Rhea)

Cofactor

Protein has several cofactor binding sites:
Mg2+ (UniProtKB | Rhea| CHEBI:18420 )

Note: Binds 1 Mg2+ ion per subunit.
Zn2+ (UniProtKB | Rhea| CHEBI:29105 )

Note: Binds 2 Zn2+ ions per homotetramer.
