The folding mechanism of a β-sheet: the WW domain
Journal of Molecular Biology, 2001The folding thermodynamics and kinetics of the Pin WW domain, a three-stranded antiparallel beta-sheet, have been characterized extensively. Folding and activation free energies were determined as a function of temperature for 16 mutants, which sample all strands and turns of the molecule.

Kinetic studies of β-sheet protein folding
Current Opinion in Structural Biology, 1998New 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 ...

Capillarity induced folding of elastic sheets
The European Physical Journal Special Topics, 2009Surface tension forces induced by a liquid droplet are used to bend thin elastic sheets into three dimensional structures. The resulting 3D shape may be controlled by tailoring the initial cut of the sheet. We derive the criterion for folding from a balance between elastic and capillary effects and compare it with the experiments. This mechanism can be

Folding of beta-sheet proteins.
Current opinion in structural biology, 1996In the past year, interesting new information concerning various aspects of the folding process of beta-sheet proteins has been gleaned. Kinetic and equilibrium folding intermediates have been characterized. Studies of extensively denatured states and of model peptide fragments have enabled important steps to be taken towards an understanding of the ...

A continuous folding process for sheet materials
International Journal of Materials and Product Technology, 2004In this paper, we present a new and innovative sheet material folding technology and the associated advances in folding different patterns using continuous manufacturing techniques. A novel approach is developed for the continuous folding process where sheet material is progressively folded in two dimensions, through a set of rollers, followed by a ...

Elasto-plastic folding of thin sheets
Acta Mechanica, 1987A thin sheet is folded by three methods. An elastic-perfectly plastic moment-curvature relationship is assumed. A plastic hinge occurs whenever the local curvature is larger than a critical value. The problem is solved by both numerical integration and asymptotic expansions. The character of the sheet changes distinctly after plasticity sets in.
