In nematodes, a fraction of mRNAs contains a common 22 nucleotide 5' terminal spliced leader (SL) sequence derived by trans splicing. Here, we show that a cell-free extract prepared from developing embryos of the parasitic nematode Ascaris lumbricoides catalyzes accurate and efficient SL addition to a synthetic pre-mRNA at an authentic trans splice acceptor site. SL addition occurs via a trans splicing reaction that proceeds through Y-branched intermediates. The branchpoint is located at either of two adenosine residues located 18 and 19 nucleotides upstream of the splice acceptor site.
