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.

Biological systems have long been known to utilize two processes for energy conservation: substrate-level phosphorylation and electron transport phosphorylation. Recently, a new bioenergetic process was discovered that increases ATP yields: flavin-based electron bifurcation (FBEB). This process couples an energetically favorable reaction with an energetically unfavorable one to conserve energy in the organism. Currently, the mechanisms of enzymes that perform FBEB are unknown. In this work, NADH-dependent reduced ferredoxin:NADP+ oxidoreductase (Nfn), a FBEB enzyme, is used as a model system to study this phenomenon. Nfn is a heterodimeric enzyme that reversibly couples the exergonic reduction of NADP+ by reduced ferredoxin with …
