Recent solution structures of RNA and its complexes with drugs, peptides and proteins.

The past two years have seen remarkable progress in the study of RNA structure: the predicted era of RNA structural biology has arrived. Crystallographic structures of the hammerhead ribozyme and of a large subunit of a group I self-splicing intron have begun to reveal the structural basis of RNA enzymatic activity. A remarkable number of structures of small RNAs and of complexes with drugs, peptides and one protein domain have been determined by NMR.
