RNA splicing, via transesterification reactions
spliceosomal catalysis
GO:0000375
pre-mRNA splicing factor activity
Note that nuclear mRNA, Group I, Group II, and Group III introns are all spliced by a series of two transesterification reactions that occur within the RNA itself, or between two RNAs in trans splicing. Some of these require one or more proteins to stabilize the catalytic conformation, while others are autocatalytic. Note that tRNA introns are spliced by a different catalytic mechanism.
