ENTRY       EC 3.1.27.9
NAME        tRNA-intron endonuclease
CLASS       Hydrolases
            Acting on ester bonds
            Endoribonucleases producing other than 5'-phosphomonoesters
REACTION    Endonucleolytic cleavage of pre-tRNA, producing 5'-hydroxyl and
            2',3'-cyclic phosphate termini, and specifically removing the
            intron.
SUBSTRATE   Pre-tRNA
            H2O
PRODUCT     5'-Hydroxyoligoribonucleotide
            2',3'-Cyclicphosphooligoribonucleotide
            tRNA
COMMENT     The enzyme catalyses the final stage in the maturation of tRNA
            molecules.
