Single Protein Dimers Observed Wavering Between Two Symmetrically Opposed Structures

Researchers have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the protein's chemical environment. One folded form is active and the other is inactive, but the protein can easily morph from one state to another.
