title: RNA structure, metal ions, and catalysis.
abstract: Several new and unexpected insights into the metalloenzymology of ribozymes have been achieved in the past year. From a mechanistic point of view, the NMR and crystal structures of a small Pb(2+)-dependent ribozyme have been particularly revealing.
