Investigating The Impact Of Small Molecule Ligands And The Proteostasis Network On Protein Folding Inside The Cell, Karan Hingorani

Doctoral Dissertations

The folded forms of most proteins are critical to their functions. Despite the complexity of the cellular milieu and the presence of high-risk deleterious interactions, there is a high level of fidelity observed in the folding process for entire proteomes. Two important reasons for this are the presence of the quality control machinery consisting of chaperones and degradation enzymes that work jointly to optimize the population of the folded state and interaction partners that re-enforce the functional state and add to the competitive advantage of an organism. While substantial effort has been directed to understand protein folding and interactions in ...

Exploring The Impact Of The E. Coli Proteostasis Network On The Folding Fate Of Proteins With Different Intrinsic Biophysical Properties, Kristine Faye R. Pobre

Doctoral Dissertations

The three-dimensional (3D) native structure of most proteins is crucial for their functions. Despite the complex cellular environment and the variety of challenges that proteins experience as they fold, proteins can still fold to their native states with high fidelity. The reason for this is the presence of the cellular proteostasis network (PN), consisting of molecular chaperones and degradation enzymes, that collaborates to maintain proteostasis, in which the necessary levels of functional proteins are optimized. Although extensive research has been carried out on the mechanisms of individual components of the proteostasis network, little is known about how these components contribute ...
