Splicing of pre-tRNAs is catalyzed by proteins, not by RNAs.

#Unit 3. Fundamental Processes

A pre-tRNA intron is excised in one step 

Finally, hydrolysis of GTP and ATP is required to join the two tRNA halves generated by cleavage on either side of the intron.

There are two classes of snoRNPs involved in rRNA processing in nucleolus. 

The box H/ACA snoRNPs are involved in pseudouridylylation, and box C/D snoRNPs function in 2-O-methylations.
