title: Hammerhead ribozyme structure: U-turn for RNA structural biology.
abstract: Two crystal structures of the hammerhead ribozyme provide the first atomic-resolution views of an RNA active site, and suggest that the catalytic center may reside in a U-turn motif which was first seen in tRNA(Phe).
