Abstract excerpt
BACKGROUND: The structure of P4-P6, a 160 nucleotide domain of the self-splicing Tetrahymena thermophila intron, was solved previously. Mutants of the P4-P6 RNA that form a more stable tertiary structure in solution were recently isolated by successive rounds of in vitro selection and amplification. RESULTS: We show that a single-site mutant (Delta C209) possessing greater tertiary stability than wild-type P4-P6...
