Legacy Theses & Dissertations (2009 - 2024)
Nuclear Magnetic Resonance Spectroscopy (NMR) is one of the principle tools in structural biology to probe macromolecular structures and interactions. The atomic resolution afforded by this technique has been widely used to probe protein-protein, and protein-ligand interactions in-vitro. However, the natural milieu of the proteins is the living cell and the cellular cytoplasm is extremely heterogeneous. The NMR studies of folded protein in-cell, till now, have been limited by non-specific interactions of the cytosol. This thesis outlays a general methodology to study protein structure/interactions inside the living cells using NMR. In a closely related objective, it also describes the use …

Discovery of the regulatory roles of non-protein coding RNAs (ncRNAs), once considered “junk” or “transcriptional noise”, has prompted a reassessment of the significance of the multifaceted activities of RNA in cellular response, which can result in cell transformation and diseased states. This reassessment, however, can only be accomplished if techniques are developed to capture, characterize and quantify the more than 100 covalent post-transcriptional modifications (PTMs) that adorn natural RNAs. Undoubtedly, the creation of high-throughput platforms such as next-generation sequencing and RNA-seq have provided unparalleled accuracy and sensitivity, however, they rely on strand amplification procedures that are blind to the known …

Simulations of biochemical systems are being increasingly used to further our understanding of those systems. In broad strokes, chemical simulations can be broken into two categories, those that are rooted in a quantum mechanical approach and those that are classically rooted. Molecular dynamics is one such classical method, which propagates motion of a chemical system via repeatedly solving Newton’s Laws of motion. This approach is less computationally intensive than the quantum mechanical methods and allows for the simulation of systems of tens of thousands of atoms, if not more.
