PubMed Abstract:
Free group II introns are infectious retroelements that can bind and insert themselves into RNA and DNA molecules via reverse splicing. Here we report the 3.4-A crystal structure of a complex between an oligonucleotide target substrate and a group IIC intron, as well as the refined free intron structure. The structure of the complex reveals the conformation of motifs involved in exon recognition by group II introns.
