Implications Of Acetylation And Phosphorylation On Metabolic Enzymes, Nour Fatema

Graduate Theses and Dissertations

All living things depend on glycolysis and the TCA cycle for energy production and metabolic control. Post-translational modifications (PTMs) such as acetylation and phosphorylation, which can change enzyme activity, substrate binding, and overall metabolic balance, tightly regulate these pathways. Diseases like cancer and metabolic problems are associated with disruptions in these alterations.

Serine phosphorylation and lysine acetylation are two of the many PTMs that are evolutionarily conserved processes that alter protein function. Previously thought to be a static histone alteration, acetylation is now understood to be a dynamic regulator of metabolic enzymes that modifies contacts, charge, and conformation. In response …

Examining Stable Isotope Variation Of Herbivores In South Luangwa Valley In The Context Of Anthropogenic Influences, Taylor Hubbard

Graduate Theses and Dissertations

Stable isotopes are an effective tool for inferring mammalian behavior. Though there are multiple factors that can influence mammalian diets, anthropogenic influence is one that is often overlooked. For example, it is important to consider how wildlife living in areas where there are frequent, documented human-wildlife interactions will modify behavior. National Parks (NPs) are a great example of this because of the common misconception that since there are protections in place, that means it is devoid of anthropogenic influence. South Luangwa National Park contradicts this misconception. Though there are protections for wildlife in place within the park, it is unfenced …

Assessment Of Nitrogen Source Utilization During Nitrogen Fixation And Nitrogenase Regulation By Methanosarcina Acetivorans, Avery Carter

Biological Sciences Undergraduate Honors Theses

Nitrogen is a crucial element in biomolecules such as proteins and DNA, essential for all cellular life. Biological nitrogen fixation, a process utilized by certain bacteria and archaea, reduces dinitrogen (N₂) to ammonia (NH₃), enabling growth in the absence of fixed nitrogen sources like NH₃. This process is driven by the metalloenzyme nitrogenase, which catalyzes the reaction: N₂ + 16ATP + 8e⁻ + 8H⁺ → 2NH₃ + H₂ + 16ADP + 16Pi. Due to its high energy demand, nitrogenase production and activity are tightly regulated. Among archaea, nitrogenase is found exclusively in methanogens, where its regulation remains poorly understood. We …

An Analysis Of Cellular And Tissue Function Of Lipin In Drosophila Melanogaster, Judah Christian Scott

Graduate Theses and Dissertations

Regulation of energy expenditure and energy storage is a key characteristic of life. Numerous enzymes play a crucial role in regulating energy metabolism. Lipins are a highly conserved family of proteins that function in both lipid synthesis and gene regulation. In the glycerol-3 phosphate pathway, lipins act as a phosphatidate phosphatase (PAP) producing diacylglycerol. In gene regulation, lipins act as transcriptional co-regulators of metabolic genes. The enzymatic PAP activity occurs in the cytoplasm; however, for lipins to function as gene regulators, they must translocate into the nucleus. Nuclear translocation is facilitated by the nuclear localization signal (NLS) within the protein. …
