obsolete tRNA exon ligation utilizing 2',3' cyclic phosphate of 5'-exon as source of linkage phosphate (obsolete GO:0000971)
OBSOLETE. A tRNA exon ligation process in which the splice junction phosphate is derived from the 2',3' cyclic phosphate at the 3'-end of the 5'-exon. This type of ligation to rejoin the 5' and 3' exons of a tRNA is observed in wheat, Chlamydomonas, and vertebrate species including humans.
