label: 3'-tRNA processing endoribonuclease activity
label_lc: 3'-trna processing endoribonuclease activity
description: "Catalysis of the 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."
