Modeling active RNA structures using the intersection of conformational space: application to the lead-activated ribozyme.

The Pb2+ cleavage of a specific phosphodiester bond in yeast tRNA(Phe) is the classical model of metal-assisted RNA catalysis. In vitro selection experiments have identified a tRNA(Phe) variant, the leadzyme, that is very active in cleavage by Pb2+. We present here a three-dimensional modeling proto...
