Protein

tRNA-splicing endonuclease

Gene

endA

Organism
Sulfolobus islandicus (strain M.16.4 / Kamchatka #3)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Endonuclease that removes tRNA introns. Cleaves pre-tRNA at the 5'- and 3'-splice sites to release the intron. The products are an intron and two tRNA half-molecules bearing 2',3' cyclic phosphate and 5'-OH termini. Recognizes a pseudosymmetric substrate in which 2 bulged loops of 3 bases are separated by a stem of 4 bp.UniRule annotation

Catalytic activityi

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.UniRule annotation

Interactioni

Subunit structurei

Homotetramer; although the tetramer contains four active sites, only two participate in the cleavage. Therefore, it should be considered as a dimer of dimers.UniRule annotation
