== Publication Abstract from PubMed ==

The VS ribozyme is a 154 nucleotide sequence found in certain natural strains of Neurospora. The RNA can be divided into a substrate and a catalytic domain. Here we present the solution structure of the substrate RNA that is cleaved in a trans reaction by the catalytic domain in the presence of Mg2+. The 30 nucleotide substrate RNA forms a compact helix capped by a flexible loop. The cleavage site bulge contains three non-canonical base-pairs, including an A+.C pair with a protonated adenine. This adenine (A622) is a pH controlled conformational switch that opens up the internal loop at higher pH. The possible significance of this switch for substrate recognition and cleavage is discussed.
