A conserved base pair within helix P4 of the Tetrahymena ribozyme helps to form the tertiary structure required for self-splicing.
Site-specific mutagenesis of the self-splicing Tetrahymena intron has been used to investigate the function of C109-G212, a conserved base pair in the P4 stem of group I introns. Mutation of C109 to G affects splicing only slightly, whereas mutation of G212 to A or C reduces the rate of splicing sub...
