Function

function

Zinc phosphodiesterase, which displays some tRNA 3'-processing endonuclease activity. Probably involved in tRNA maturation, by removing a 3'-trailer from precursor tRNA.

Catalytic activity

  • Endonucleolytic cleavage of RNA, removing extra 3' nucleotides from tRNA precursor, generating 3' termini of tRNAs. A 3'-hydroxy group is left at the tRNA terminus and a 5'-phosphoryl group is left at the trailer molecule.
    EC:3.1.26.11 (UniProtKB | ENZYME | Rhea)

Cofactor

Zn2+ (UniProtKB | Rhea| CHEBI:29105 )

Note: Binds 2 Zn2+ ions.
