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 gradformat@asu.edu.


Like most other phototrophic organisms the cyanobacterium Synechocystis sp. PCC 6803 produces carotenoids. These pigments often bind to proteins and assume various functions in light harvesting, protection from reactive oxygen species (ROS) and protein stabilization. One hypothesis was that carotenoids bind to the surface (S-)layer protein. In this work the Synechocystis S-layer protein was identified as Sll1951 and the effect on the carotenoid composition of this prokaryote by disruption of sll1951 was studied. Loss of the S-layer, which was demonstrated by electron microscopy, did not result in loss of carotenoids or changes in the carotenoid profile of the mutant, which …

Synthetic biology is constantly evolving as new ideas are incorporated into this increasingly flexible field. It incorporates the engineering of life with standard genetic parts and methods; new organisms with new genomes; expansion of life to include new components, capabilities, and chemistries; and even completely synthetic organisms that mimic life while being composed of non-living matter. We have introduced a new paradigm of synthetic biology that melds the methods of in vitro evolution with the goals and philosophy of synthetic biology. The Family B proteins represent the first de novo evolved natively folded proteins to be developed with increasingly powerful …
