“Although Mg (2+) and tobramycin are relatively simple ligands, both modulate tRNA ( Asp ) folding in unanticipatedly complex ways, neither of which is consistent with simple hierarchical folding or unfolding of this RNA.”
“The tobramycin polycation binds to loops in tRNA ( Asp ) and induces RNA unfolding in two distinct transitions: the loss of tertiary interactions between the T- and D-loops followed by complete unfolding of the D-stem.”
