Structural Elucidation Of Aggr-Activated Regulator, Aar, In Enteroaggregative Escherichia Coli, Andrew Heindel
Structural Elucidation Of Aggr-Activated Regulator, Aar, In Enteroaggregative Escherichia Coli, Andrew Heindel
Senior Honors Projects, 2010-2019
Travelers’ Diarrhea is the number one cause of childhood death in the world. Enteroaggregative Escherichia coli (EAEC) is one of the main causes of this disease. EAEC adhere to the surface of the intestine and stack in a brick-like pattern. Via an unstudied quorum-sensing mechanism, these bacteria express a variety of virulence factors that lead to diarrhea. The long-term goal of this research is to elucidate the mechanism by which EAEC changes from benign to virulent. A previously-unstudied open-reading frame in EAEC, AggR activated repressor (Aar), has recently been hypothesized to act as one of the major transcription factors influencing …
Conformational Heterogeneity And Exchange Within The Junction Of The Human U2-U6 Snrna Complex Measured By 19f Nmr Spectroscopy, Caijie Zhao
Dissertations, Theses, and Capstone Projects
Pre-mRNA splicing, the process by which non-coding sequences are removed and coding sequences are ligated, plays an important role in the maturation of precursor messenger RNA molecules prior to their translation into proteins. In eukaryotes, splicing is catalyzed by the spliceosome, a large and dynamic nuclear macromolecular "machine" that comprises five small nuclear (sn)RNA molecules and more than one hundred proteins. Among the RNA components, the complex formed between the U2 and U6 snRNA molecules is implicated in catalytic activity. In this dissertation, I have used 19F NMR techniques to characterize the conformation ("fold") and dynamics of a protein-free …

The Critical Assessment of protein Structure Prediction (CASP) experiment would not have been possible without the prediction targets provided by the experimental structural biology community. In this article, selected crystallographers providing targets for the CASP11 experiment discuss the functional and biological significance of the target proteins, highlight their most interesting structural features, and assess whether these features were correctly reproduced in the predictions submitted to CASP11.

SMRT/HDAC Associated Repressor Protein interacts with the long noncoding RNA, produced by SRA, by binding at the RRMs. Three projects were done to prepare the truncated proteins for use in 2D and 3D NMR experiments. The first focuses on RRM 3 and its optimization during the purification process. The second focuses on RRM 2-4, which was found to be missing two alpha helices that may be important for protein stability. These helices can also interact with RRM 3 as well due to the tight association of RRMs 3 and 4. The two step PCR extension of RRM 2-4 was assumed …
