 The SL RNA provides an exon that is connected to the first exon of an mRNA by trans-splicing. The reaction involves the same interactions as nuclear cis splicing but generates a Y-shaped RNA instead of a lariat.

Disulfide bonds are believed to increase the stability of the native state by decreasing the conformational entropy of the unfolded state due to the conformational constraints imposed by cross-linking (i. e. decreasing the free energy of the unfolded state).
