When an amino-acid sequence cannot be optimized for both folding and function, folding can get compromised in favor of function. To understand this tradeoff better, we devise a novel method for extracting the "function-less" folding-motif of a protein fold from a set of structurally similar but functionally diverse proteins. We then obtain the β-trefoil folding-motif, and study its folding usin...
Recently, several innovative approaches have been developed that allow one to directly screen or select for improved protein folding in the cellular context. These methods have the potential of not just leading to a better understanding of the in vivo folding process, they may also allow for improved production of proteins of biotechnological interest.
Three out of 125 “big questions of science”, can now be claimed to have been answered. All of these questions involve water; its structure, its role in protein folding and its role in protein-protein association.
We describe a conceptual framework for understanding the way large RNA molecules fold based on the notion that their free-energy landscape is rugged. A key prediction of our theory is that RNA folding can be described by the kinetic partitioning mechanism (KPM). According to KPM a small fraction of molecules folds rapidly to the native state whereas the remaining fraction is kinetically trapped...
High-intensity, "pink" beam from an undulator was used in conjunction with microfabricated rapid-fluid mixing devices to monitor the early events in protein folding with time resolved small angle x-ray scattering. This Letter describes recent work on the protein bovine beta-lactoglobulin where collapse from an expanded to a compact set of states was directly observed on the millisecond time sca...
