Sammanfattning : Going down the folding funnel, proteins may sample a wide variety of conformations, some being outright detrimental to the organism. Yet, the vast majority of polypeptide molecules avoid such pitfalls. Not only do they reach the native minimum of the energy landscape; they do so via blazingly fast, biased, routes. LÄS MER
2. The birth and growth of the protein folding nucleus : Studies of protein folding focused on critical contacts, topology and ionic interactions
Sammanfattning : Proteins are among the most complex molecules in the cell and they play a major role in life itself. The complexity is not restricted to just structure and function, but also embraces the protein folding reaction. LÄS MER
3. Folding of the Ribosomal protein S6 : The role of sequence connectivity, overlapping foldons, and parallel pathways
Sammanfattning : To investigate how protein folding is affected by sequence connectivity five topological variants of the ribosomal protein S6 were constructed through circular permutation. In these constructs, the chain connectivity (i.e. the order of secondary-structure elements) is changed without changing the native-state topology. LÄS MER
Sammanfattning : The interaction between two 6 kDa proteins has been investigated. The studied complex of micromolar affinity (Kd) consists of the Z domain derived from staphylococcal protein A and the related protein ZSPA-1, belonging to a group of binding proteins denoted affibody molecules generated via combinatorial engineering of the Z domain.

Sammanfattning : Sequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. LÄS MER
