3CZW, 3D0M - PubMed Abstract: 
The structures of two crystal forms of the RNA 16-mer with the sequence GUGGUCUGAUGAGGCC, grown in the presence of a high concentration of sulphate ions, have been determined using synchrotron radiation at 1.4- and 2.0-A resolution. RNA with this sequence is known as one of the two strands of the noncleavable form of the hammerhead ribozyme ...
