This step is similar to other small self-cleaving ribozymes such as the Hammerhead ribozyme and HDV ribozyme. Both of those ribozymes generate a product, which contain a 2’, 3’ -cyclic phosphate.
Similar to other compact self-cutting ribonucleases, this step is akin to the mechanisms employed by the Hammerhead ribozyme and HDV ribozyme. These ribozymes yield a product featuring a 2’, 3’ -cyclic phosphodiester bond.
