Precatalytic Intron Structure Solved
The first crystal structure of the precatalytic state of a group II intron has been solved (Nat. Struct. Mol. Biol., DOI: 10.1038/nsmb.2270). Previous structures of these self-splicing RNA molecules, which are thought to be evolutionary predecessors of the spliceosome, have captured them either during or after the splicing process, but never before splicing starts.
