Many tRNAs undergo tertiary folding transitions at temperatures well below the main thermally induced (hyperchromic) transition. Such transitions are essentially isochromic and isoenthalpic and display an absolute requirement for divalent cations; however, the nature of the structural transition is not known for any tRNA. Using a combination of transient electric birefringence (TEB) and gel electrophoretic measurements, we have characterized the influence of magnesium ions on the apparent angle… CONTINUE READING
