ASU Electronic Theses and Dissertations

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at

Solution conformations and dynamics of proteins and protein-DNA complexes are often difficult to predict from their crystal structures. The crystal structure only shows a snapshot of the different conformations these biological molecules can have in solution. Multiple different conformations can exist in solution and potentially have more importance in the biological activity. DNA sliding clamps are a family of proteins with known crystal structures. These clamps encircle the DNA and enable other proteins to interact more efficiently with the DNA. Eukaryotic PCNA and prokaryotic β clamp are two of these clamps, some of the most stable homo-oligomers known. However, their …

The primary carbon fixing enzyme Rubisco maintains its activity through release of trapped inhibitors by Rubisco activase (Rca). Very little is known about the interaction, but binding has been proposed to be weak and transient. Extensive effort was made to develop Förster resonance energy transfer (FRET) based assays to understand the physical interaction between Rubisco and Rca, as well as understand subunit exchange in Rca. Preparations of labeled Rubisco and Rca were utilized in a FRET-based binding assay. Although initial data looked promising, this approach was not fruitful, as no true FRET signal was observed. One possibility is that under …
