Mechanism Of Sila- And Germafluorenes For Biological Applications, Shelby Jarrett
Mechanism Of Sila- And Germafluorenes For Biological Applications, Shelby Jarrett
Dissertations
2,7-disubstituted silafluorenes and germafluorenes, originally designed for OLED applications, are a class of fluorescent dyes that have gained recent interest as probes for bioimaging and as biosensors to monitor cellular dynamics and interactions. Desirable biological probes absorb in the visible region, have high extinction coefficients, high quantum yield and excellent photostability. Here, their spectral properties are investigated under aqueous conditions for relevant biological applications. These molecules display intense blue fluorescence in the solid state and in solution, have high extinction coefficients, and exhibit appreciable solubility in aqueous solution. To better understand potential applications, the mechanism of fluorescence was investigated. It …
Investigation Of The Binding Domain Interfaces Of The C-Terminus Of The Albino3 Insertase And The 43kda Chloroplast Signal Recognition Particle Subunit Via Single Molecule Förster Resonance Energy Transfer, Amanda Tomanek
Chemistry & Biochemistry Undergraduate Honors Theses
Fluorescent labeling is a technique used for visualizing functional groups contained in biomolecules by fluorescence imaging. This technique was used in this project to analyze post-translational targeting of light-harvesting chlorophyll-binding proteins (LHCP), which are the core complexes that harvest sunlight to drive photosynthetic electron transfer. This protein is synthesized in the cytosol and post-translationally targeted to the stroma of chloroplasts. CpSRP43 is a signal recognition particle (SRP) subunit unique to chloroplasts, which has been shown to interact with the stroma-soluble C-terminus of the thylakoid-bound Albino3 insertase (Alb3-Cterm). In the chloroplast stroma, targeting to thylakoids is performed via the cpSRP pathway …
Investigating The Main Protease (Mpro) Of Sars-Cov-2 As A Potential Drug Target, Valerie Giovina Pascetta
Investigating The Main Protease (Mpro) Of Sars-Cov-2 As A Potential Drug Target, Valerie Giovina Pascetta
Honors Theses and Capstones
The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the coronavirus disease 19 (COVID-19) pandemic has claimed the lives of roughly 6.2 million people worldwide as of May 2022. The virus’s main protease (Mpro ) has been identified as an attractive drug target due to the critical role it plays in the viral life cycle. The roughly 34 kDa Mpro cleaves functional viral polypeptides out of two long polyproteins at conserved cut sites, allowing them to fulfill their role in processes like transcription and replication. Here, we have studied the enzymatic activity …
