While the biosynthesis of the polymers constitutes of three major steps, the last reaction of the pathway catalyzed by branching enzyme embodies the cleavage of the α-1,4 glycosidic bond and the transfer of the produced oligosaccharide to the specific α-1,6 position creating an α-1,6 branch point. This process results in highly branched polymeric structures, which represent major carbon sources and carbohydrate storage compounds in living organisms, and are essential both in nature and industry. The structure of Escherichia coli glycogen branching enzyme has been solved both in the apo and holo forms. Binding to linear and cyclic oligosaccharides has been studied and showed seven external binding sites, but binding in the active site was not seen. Oligomers longer than previously used were investigated in an attempt to see binding in the catalytic center, only to discover more peripheral binding sites seemingly independent of each other. Examining the binding sites’ locations and sugars’ orientations indicates that these sites probably cooperate together in order to hold the long sugar polymer on the surface of the protein during the branching reaction. Hypotheses regarding the mode of binding between E. coli branching enzyme and the sugar during the reaction, and the roles for key binding sites and residues in the mechanism are proposed.Rice branching enzyme I, a starch branching enzyme, was also previously crystallized and the structure of the truncated version was solved. Binding attempts on this protein showed surface binding sites as well. In an effort to better understand the mechanism of action of this enzyme, we crystallized the protein and soaked it in a 12-unit oligomer, which bound to the enzyme hanging over the active site without reaching into the groove. Two new binding sites were discovered for this protein and the residues involved were identified. There are several hydrogen bonds and aromatic stacking interactions within the binding sties. Hypotheses for the binding mode and reaction mechanism are proposed.In addition, we have worked on ADP-glucose pyrophosphorylases that catalyze the first step in the biosynthesis pathway. The small subunit of the protein expresses as a homotetramer that is highly active. Although the potato tuber form was previously expressed in a collaborating laboratory at extremely small levels, and the protein was crystallized in the inactive form in the Geiger lab, our intensive attempts only succeeded in purifying the protein of interest, but the enzyme would precipitate instead of concentrating.

Show moreInWriting the Archives: Context, Materiality, Identity , I develop a theoretical and methodological framework for studying archives as institutions that reproduce the rhetorics and identities of particular cultures. This framework includes four key arguments: 1) Archives are constituted through a selective and subjective process of appraisal; 2) What counts as "historical" or even "archival" depends on the attitudes and values of the cultures that create archives; 3) Archivists depend on communicative processes such as writing in order to organize and frame the materials in their care. These processes are culturally-situated and are not the same across all archival spaces; 4) Archives are material spaces that bear very little resemblance to the metaphorical notions of "The Archive" developed by theorists such as Thomas Richards, Diana Taylor, Michel Foucault etc. Central to this framework is the idea that all archives are different since they are constituted by communities whose experiences in the world are unique and different. I argue that my framework for understanding archives would allow us to create better archival research methodologies and also help us better train students who are interested in archival research at the graduate and undergraduate level.I employ a mixed method approach for understanding the role of archives in the constitution of communities and identities. These methods include oral history interviews with archivists who have worked at sites such as the archives as the University of Illinois at Urbana- Champaign and the Lesbian Herstory Archives. A close analysis of these interviews and these sites reveals that archives are built in order to produce particular kinds of communityengagement. Decisions pertaining to the materials collected by these archives and access to these materials depend on the communal and identity politics of these institutions.Additionally, I closely analyze finding aids from the above archives in order to show how they communicate the original context surrounding the production and circulation of archival records. I argue that that the contextual information offered by archival finding aids is always partial in nature. As such, finding aids are rhetorical artifacts because they build histories and identities for archival materials that affect the way in which these materials are read and interpreted by researchers. Finding aids frame researchers' knowledge of archival collections since they provide contextual information about how and where records were produced. I further demonstrate how western models of archival finding aids have been complicated by GLBTQ communities and indigenous communities; these communities argue for more egalitarian finding aids that acknowledge multiple record creators and stakeholders.Lastly, I analyze the digitization practices of two digital archives, namely the Digital Archives of Literacy Narratives and the Blake Archive. I draw from the work of digital humanists and archivists to argue that in the context of digital archives, digitization of records is a cultural process. The manner in which we choose objects to be digitized reflects our biases, and it is never an "objective" process. As such, I argue that digitization is a rhetorical process because it creates culturally-mediated representation of a material object. I also point out that digitization does not necessarily mean that an archival record has been "preserved." All digitized records have unique identities and histories that need to be preserved as well. Therefore, I argue that archival digitization should attempt to connect records with their material counterparts in order to create a holistic representation of the original context in which records were produced and circulated.

Show moreThe study of writing within industrial workplaces has been taken up by many disciplines and focuses of study, such as technical writing, engineering, management, literacy studies, and literacy education, to name a few. Industrial workplaces are highly complex--with machinery, robots, floor workers, engineers, and managers all working together--making them fantastic locations for studies of power, authority, labor, and text. In addition, industrial workplaces like factories represent labor histories as well as the changing economic environment of the U.S., often making them a locus for both research and nostalgia. My own interest in conducting writing study research in factories is this locus of scholarship and nostalgic memory, for factory work is part of my family's identity. I explored existing literature on factory workplaces and the writing that is done there, with the goal to merge an interest in writing with working-class upbringing. I found a gap in the literature that troubled me--where was the research that focused on the shop floor workers and their writing? Where were the studies that viewed such individuals not as people who do not and cannot write but as important knowledge makers (the way I view my dad)? Then I wondered, in the complex physical and social environment of factories, what kinds of texts do shop floor workers write and how do they develop those texts? This dissertation grew out of my desire to answer the questions of what and how factory workers write. I developed a research approach that I call "case-study with a phenomenological sensibility" to help me, and through this research methodology I was able to learn about the writing experiences of two factory machine operators at a Post Cereals plant in Battle Creek, Michigan. Through the interviews I conducted I learned that, in the cases of the two particular machine operators I worked with, their workplace writing practices and processes were shaped almost entirely by the time and resource regulations of the factory. I also discovered that because both operators were highly invested in their work already, they felt pride and a sense of being valued when they shared their knowledge through writing. What this dissertation offers, then, is a glimpse into the workplace writing lives of two factory machine operators. Turning the research gaze to writing that these operators did on the factory floor reveals how the changing nature of industry--a national and global issue--has influenced the everyday working activities of factory floor laborers. More specifically, my own research gaze has revealed the growing importance for collaboration in writing in traditionally hierarchical factories, benefits gained through writing about work practices, and the significance of personal investment in the workplace lives of two factory workers. Though the claims made in this work are narrow in focus, they provide strong evidence for a need to focus industrial workplace writing research on all hierarchical levels, including the blue-collar laborer.

Show moreThis dissertation explores the effects of settler colonialism on Great Lakes Indigenous peoples throughout the nineteenth century. It argues that as settler societies dispossessed Indigenous peoples from their lands in order to gain access to natural resources, they engaged in a process of narrative erasure of those Indigenous peoples in order to justify the violence of dispossession. This narrative tool of settler colonists was also employed in assertions of what I call “frontier nationalism” to argue for the prominence of frontier societies in the public arena of print culture in an age when citizens of both the young United States and Canada were debating the characteristics of national identity. From territorial and colonial administrators like Lewis Cass and Sir Francis Bond Head to frontier novelists like Juliette Kinzie in Chicago and Major John Richardson in Upper Canada to antiquarian historians who wrote local and regional histories of the Great Lakes region, and ultimately to professional historians like Frederick Jackson Turner, Great Lakes authors constructed a narrative that celebrated the growth and progress of life on the frontier in a manner that mythologized the region’s Indigenous peoples out of existence. In the meantime, Great Lakes Indians evolved numerous strategies of resistance to both thwart dispossession and removal, and to disprove myths penned by settler society of Indigenous inferiority, incompatibility with progress and modernization, and the inevitability of Indian disappearance. Beginning with the Mohawk siblings, Molly and Joseph Brant, Great Lakes Indians developed understandings of various aspects of western culture that they adapted within their own cultural frameworks to battle the effects of settler colonialism throughout the nineteenth century. The Brants used their understanding of British legal tradition, private property rights, western plough agriculture, Christianity, literacy, and ultimately narrative construction and the public print culture to constantly prove to first British and later Americans that they were capable of adhering to western standards of “civilization.” Learning from the legacy passed on by the Brants, adopted Mohawk war chief John Norton, Mississauga chief Peter Jones, and Potawatomi chief Leopold Pokagon all used their own understandings of western expectations for Indigenous peoples to prove they were deserving of governmental exceptions to policies of Indian removal. Throughout the nineteenth century, Great Lakes Indians responded to the settler colonial violence of narrative construction and Indigenous erasure by turning to the world of print. John Norton wrote a history of the Haudenosaunee just after the War of 1812 that he intended for publication though it wound up on a shelf for over a century. Peter Jones also wrote a manuscript on the history of the Ojibwe people that he intended to publish, but because of his early death, it was later published by his wife. Leopold Pokagon’s son Simon earned the most acclaim in his lifetime, publishing numerous works including his novel, Queen of the Woods, and his Red Man’s Rebuke, which he printed on birchbark paper and distributed at the 1893 World’s Columbian Exposition in Chicago. This dissertation argues that these writings all serve as evidence of the survivance of Great Lakes Indians in the midst of a settler colonial impulse to eradicate Indigenous peoples from the landscape and historical memory.
