The glmS ribozyme is the only natural catalytic RNA known to require a, small-molecule activator for catalysis. This catalytic RNA functions as a, riboswitch, with activator-dependent RNA cleavage regulating glmS, messenger RNA expression. We report crystal structures of the glmS, ribozyme in precleavage states that are unliganded or bound to the, competitive inhibitor glucose-6-phosphate and in the postcleavage state., All structures superimpose closely, revealing a remarkably rigid RNA that, contains a preformed active and coenzyme-binding site. Unlike other, riboswitches, the glmS ribozyme binds its activator in an open, solvent-accessible pocket. Our structures suggest that the amine group of, the glmS ribozyme-bound coenzyme performs general acid-base and, electrostatic catalysis.
