Crystal Structure of RNAse Z/tRNA(Thr) complex

Released:

Function and Biology Details

Reaction catalysed:
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.
