Re-characterization of hammerhead ribozymes as molecular tools for intermolecular RNA cleavage†
Abstract
A new guideline for the construction of hammerhead ribozymes to achieve trans-cleavage of a single-stranded RNA molecule was developed. The sequence rule of the HHRz cleavage site was highly recommended to be “DWH” with an optimal binding arm length of 8–9nt, which diverged from the former rule of “NUX”.
