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.

A novel small metal-binding protein (SmbP), with only 93 residues and no similarity to other known proteins, has been isolated from the periplasm of Nitrosomonas europaea. It is characterized by its high percentage (17%) of histidines, a motif of ten repeats of seven residues, a four α-helix bundle structure, and a high binding affinity to about six equivalents of Cu2+. The goal of this study is to investigate the Cu2+ binding sites in SmbP and to understand how Cu2+ stabilizes the protein. Preliminary folding experiments indicated that Cu2+ greatly stabilizes SmbP. In this study, protein folding data from circular dichroism …

Glycosaminoglycans (GAGs) are a class of complex biomolecules comprised of linear, sulfated polysaccharides whose presence on cell surfaces and in the extracellular matrix involve them in many physiological phenomena as well as in interactions with pathogenic microbes. Decorin binding protein A (DBPA), a Borrelia surface lipoprotein involved in the infectivity of Lyme disease, is responsible for binding GAGs found on decorin, a small proteoglycan present in the extracellular matrix. Different DBPA strains have notable sequence heterogeneity that results in varying levels of GAG-binding affinity. In this dissertation, the structures and GAG-binding mechanisms for three strains of DBPA (B31 and N40 …

The ability to manipulate the interaction between small molecules and biological macromolecules towards the study of disease pathogenesis has become a very important part of research towards treatment options for various diseases. The work described here shows both the use of DNA oligonucleotides as carriers for a nicotine hapten small molecule, and the use of microsomes to study the stability of compounds derived to treat mitochondrial diseases. Nicotine addiction is a worldwide epidemic because nicotine is one of the most widely used addictive substances. It is linked to early death, typically in the form of heart or lung disease. A …
