In the first half of a two-step reaction, the motif uses Pb2+ to cleave the phosphodiester backbone of the substrate strand, yielding a free 5ʹ′-hydroxyl and a 2ʹ′,3ʹ′-cyclic phosphodiester as products, which is analogous to the activity catalyzed by naturally occurring small ribozymes such as the hammerhead and hairpin.

In the first half of a two-step reaction, the motif uses Pb2+ to cleave the phosphodiester backbone of the substrate strand, yielding a free 5ʹ′-hydroxyl and a 2ʹ′,3ʹ′-cyclic phosphodiester as products, which is analogous to the activity catalyzed by naturally occurring small ribozymes such as the hammerhead and hairpin. The cyclic phosphate is hydrolyzed subsequently to produce a 3ʹ′-phosphate in a manner similar to that of protein ribonuclease A.
