Topography of 5.8 S rRNA in rat liver ribosomes. Identification of diethyl pyrocarbonate-reactive sites.
The topography of 5.8 rRNA in rat liver ribosomes has been examined by comparing diethyl pyrocarbonate-reactive sites in free 5.8 S RNA, the 5.8 S-28 rRNA complex, 60 S subunits, and whole ribosomes. The ribosomal components were treated with diethyl pyrocarbonate under salt and temperature conditions which allow cell-free protein synthesis; the 5.8 S rRNA was extracted, labeled in vitro, chemi...

Diethyl pyrocarbonate: a chemical probe for DNA cruciforms.
Two palindromic DNA sequences were analyzed with respect to their chemical reactivities with diethyl pyrocarbonate. In negatively supercoiled plasmid templates enhanced N7 carbethoxylation was found with individual purines located in presumptive single-stranded loops of DNA cruciform structures. No enhanced reactivity at these positions was observed in linear, relaxed or low superhelical densit...
