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 firstname.lastname@example.org.

To mimic the membrane environment for the photosynthetic reaction center of the photoheterotrophic Heliobacterium modesticaldum, a proteoliposome system was developed using the lipids found in native membranes, as well as a lipid possessing a Ni(II)-NTA head group. The liposomes were also saturated with menaquinone-9 to provide further native conditions, given that menaquinone is active within the heliobacterial reaction center in some way. Purified heliobacterial reaction center was reconstituted into the liposomes and a recombinant cytochrome c553 was decorated onto the liposome surface. The native lipid-attachment sequence of cytochrome c553 was truncated and replaced with a hexahistidine tag. Thus, the membrane-anchoring …

Rubisco activase (Rca) from higher plants is a stromal ATPase essential for reactivating Rubiscos rendered catalytically inactive by endogenous inhibitors. Rca’s functional state is thought to consist of ring-like hexameric assemblies, similar to other members of the AAA+ protein superfamily. However, unlike other members, it does not form obligate hexamers and is quite polydisperse in solution, making elucidation of its self-association pathway challenging. This polydispersity also makes interpretation of traditional biochemical approaches difficult, prompting use of a fluorescence-based technique (Fluorescence Correlation Spectroscopy) to investigate the relationship between quaternary structure and function. Like cotton β Rca, tobacco β Rca appears to …
