Enzyme Information

4.6.1.16

tRNA-intron lyase.

based on mapping to UniProt Q9YBF1

PretRNA = a 3'-half-tRNA molecule with a 5'-OH end + a 5'-half-tRNA molecule with a 2',3'-cyclic phosphate end + an intron with a 2',3'-cyclic phosphate and a 5'-hydroxyl terminus.

-!- The enzyme catalyzes the final stage in the maturation of tRNA molecules. -!- Formerly EC 3.1.27.9.
