abstract = {A protein fold is defined as a structural arrangement of a
secondary structure in a threedimensionalspace. It would be
interesting to know whether a particular fold can be
assigned to certainfeatures of the corresponding
folding/unfolding transitions. To understand the underlying
principlesof the manifold folding transitions in more
detail, single-molecule FRET is the method of choice.Taking
the two-domain protein phosphoglycerate kinase (PGK) as an
example, we investigateddenaturant-induced unfolded states
of PGK using the above method. For this purpose,
differentintramolecular distances within the two domains
were measured. In addition to the known two-statetransition,
a transition with a compact folding intermediate was also
identified in each of the twodomains. Based on the
structural homology of the domains (characterized by a
Rossmann fold)and the striking similarity in the features of
the measured distance changes during unfolding,
clearevidence emerged that the underlying domain topology
plays an important role in determining theobserved
structural changes.},
