Defining the structural properties of the involved transient species is therefore of prime interest. Using a combination of cold denaturation with NMR spectroscopy, we reveal detailed insight into the unfolding of the homodimeric repressor protein CylR2. Seven three-dimensional structures of CylR2 at temperatures from 25 degrees C to -16 degrees C reveal a progressive dissociation of the dimeric protein into a native-like monomeric intermediate followed by transition into a highly dynamic, partially folded state. The core of the partially folded state seems critical for biological function and misfolding.
