obsolete tRNA exon ligation utilizing GTP as source of linkage phosphate (obsolete GO:0000970)
OBSOLETE. A tRNA exon ligation process in which the splice junction phosphate is derived from exogenous GTP. This type of ligation to rejoin the 5' and 3' exons of a tRNA is observed in the yeast Saccharomyces cerevisiae where the ligation reaction also produces a 2'-phosphate at the splice junction which is subsequently removed as part of the ligation process.
