- \caption{\subref{fig:folding:pathway} A ``double T'' example of the
- pathway model of protein folding, in which the protein proceeds
- from the native state $N$ to the unfolded state $U$ via a series
- of metastable transition states $I_1$ and $I_2$ with two ``dead
- end'' states $I_1^X$ and $I_2^X$. Adapted from \citet{bedard08}.
- \subref{fig:folding:landscape} The landscape model of protein
- folding, in which the protein diffuses through a multi-dimensional
- free energy landscape. Separate folding attempts may take many
- distinct routes through this landscape on the way to the folded
- state. Reproduced from \citet{dill97}.
