Surface Mutation Thr34his Facilitates Purification Of Haemophilus Influenza Carbonic Anhydrase Via Metal Affinity Chromatography, Caroline Foley, Dr. Kathleen Cornely
Chemistry & Biochemistry Student Scholarship
In order to pursue Haemophilus influenza carbonic anhydrase (HICA) as a potential drug target, easy and efficient purification methods must be developed. While immobilized metal affinity chromatography (IMAC) may be used, complications with polyhistidine tags is a concern. Inspired by the endogenous metal affinity of Escherichia coli β-carbonic anhydrase (ECCA), we suggest that the generation of histidine clusters on HICA’s surface will facilitate its purification by metal affinity chromatography without the potential interference of His-tags. Here we investigate the Thr34His mutation as a method to generate metal affinity in HICA. Since Thr34His is located only 5.3 Å away from His32, …

Legacy Theses & Dissertations (2009 - 2024)
The challenges to forensic body fluid analysis have placed limitations on the type of information that investigators can acquire and how that information can be collected. In recent years, Raman spectroscopy has proven itself useful for characterizing body fluids. In 2008, a large-scale investigation was undertaken to explore the use of Raman spectroscopy as a means of identifying body fluids. This work resulted in multidimensional Raman spectroscopic signatures for the five main body fluids: semen, peripheral blood, saliva, vaginal fluid, and sweat. These studies were incredibly successful and created the foundation for years of continued research. Accordingly, the studies included …
