title: Structural consensus of RNA templates replicated by Q beta replicase.
abstract: Q beta replicase replicates a variety of enzyme-specific small RNAs in addition to the phage genomic RNA. The sequence analysis has revealed that all these RNAs are potentially capable of forming a consensus secondary structure element. It represents a stalk which is formed by the 5'-GGG ... and ... CCCA-3' complementary stretches at the termini of the replicating RNA molecules and adjacent 5'- and 3'-hairpins, which may form a stacking with the stalk. The structure found is rather similar to the analogous structure in the tRNA molecule. The genomic RNA of the Q beta phage and other related phages can also form a similar structural element.
