The Tetrahymena intron is an RNA catalyst, or ribozyme. As part of its self-splicing reaction, this ribozyme catalyzes phosphoryl transfer between guanosine and a substrate RNA strand. Here we report the refined crystal structure of an active Tetrahymena ribozyme in the absence of its RNA substrate at 3 ...
