P.5 top paragraph: "Moreover, changes in the loop sequences induced a large reduction in the cleavage rate (<0.01/min) [ref 44], suggesting that steric clashes prevented the necessary and specific interactions for proper folding of the ribozyme. Similar results were obtained for other HHRs, including the type I HHR encoded in the satellite DNA Smα of the Schistosoma mansoni trematode [ref 46], which reached a maximum cleavage rate close to 1000/min [primary source]. Moreover, detailed kinetic analysis of the full S. mansoni HHR also revealed a 2000-fold increase in the rate of ligation compared to minimal hammerheads without tertiary interactions [ref 47]." |
