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.

The AAA+ ATPase Rubisco activase (Rca) regulates the activity of Rubisco, the photosynthetic enzyme responsible for catalyzing biological carbon fixation. However, the detailed mechanism by which Rca self-association controls Rubisco reactivation activity remains poorly understood. In this work, we are using fluorescence correlation spectroscopy (FCS) to better characterize the thermodynamics of the assembly process of cotton Rca. We present FCS data for Rca in the presence of Mg*ATPgS and Mg*ADP and for the D173N Walker B motif mutant in the presence of Mg*ATP. Our data are consistent with promotion and stabilization of hexamers by Mg*ATPgS and Mg*ATP, whereas Mg*ADP facilitates …
