RNA enzymes: putting together a large ribozyme.
The crystal structure of a 160-nucleotide domain of a ribozyme provides the first detailed view of an RNA large enough to show side-by-side packing of helices. Several new structural motifs are found: ribose zippers, adenosine platforms and a tetraloop receptor.
