Presence of a coordinated metal ion in a trans-acting antigenomic delta ribozyme.

Nucleic acids research - 1 Aug 1999

Lafontaine D A, Ananvoranich S, Perreault J P

Abstract excerpt

We have investigated the cleavage induced by metal ions in an antigenomic form of a trans-acting delta ribozyme. A specific Mg(2+)-induced cleavage at position G(52)at the bottom of the P2 stem was observed to occur solely within catalytically active ribozyme-substrate complexes (i.e. those that performed the essential conformational transition step). Only the divalent cations which support catalytic activity...
