Folding of group I introns from bacteriophage T4 involves internalization of the catalytic core.

Abstract

Fe(II)-EDTA, a solvent-based cleavage reagent that distinguishes between the inside and outside surfaces of a folded RNA molecule, has revealed some of the higher-order folding of the group IB intron from Tetrahymena thermophila pre-rRNA. This reagent has now been used to analyze the bacteriophage T4 sunY and td introns, both of which are members of the… (More)
