CC -!- FUNCTION: Constitutes one of the two catalytic subunit of the tRNA-
CC splicing endonuclease complex, a complex responsible for identification
CC and cleavage of the splice sites in pre-tRNA. It cleaves pre-tRNA at
CC the 5'- and 3'-splice sites to release the intron. The products are an
CC intron and two tRNA half-molecules bearing 2',3'-cyclic phosphate and
CC 5'-OH termini. There are no conserved sequences at the splice sites,
CC but the intron is invariably located at the same site in the gene,
CC placing the splice sites an invariant distance from the constant
CC structural features of the tRNA body. It probably carries the active
CC site for 3'-splice site cleavage (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=pretRNA = a 3'-half-tRNA molecule with a 5'-OH end + a 5'-
CC half-tRNA molecule with a 2',3'-cyclic phosphate end + an intron with
CC a 2',3'-cyclic phosphate and a 5'-hydroxyl terminus.; EC=4.6.1.16;
CC -!- SUBUNIT: tRNA splicing endonuclease is a heterotetramer composed of
CC tsp-2/sen2, tsp-1/sen15, tsp-4/sen34 and tsp-5/sen54. Interacts
CC directly with tsp-1/sen15 (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the tRNA-intron endonuclease family.
CC {ECO:0000305}.
