Abstract：
:New studies have shown that folding of beta-sheet proteins can occur with and without intermediates, with fast to slow refolding rates and late to very late transition states. These experiments demonstrate that, despite early speculation to the contrary, beta-sheet protein folding does not appear to be fundamentally different from that of helical and mixed alpha, beta proteins.
