Counting Protons: Using Isothermal Titration Calorimetry to Determine the Number of Protons Exchanged Upon Ca(II) and Cd(II) Binding to Wild-type HcTnC and Mutant C84A and C35A/C84A Proteins
Vang, Katie (East Carolina University, 2018-07-20)Maintaining a delicate balance of metal ions in the cell is crucial to the survival of many organisms. Divalent cadmium, Cd(II), is a non-essential metal ion that can disrupt this delicate balance and lead to deleterious ... -
Method Development and Validation for the Rapid Detection of Organophosphates in Blood Plasma from Obese, Obese-Diabetic, and Lean Patients from Eastern North Carolina
Bowman, Cheyenne (East Carolina University, 2017-07-13)The incidence of diabetes and rate of obesity is on the rise, along with the use of organophosphorus insecticides in the United States. Organophosphates (OP), a specific class of pesticide that is biodegradable and readily ... -
Studying Collagen with PyrATS: Pyrene-Appended Trimeric Systems
Keever, Jared Matthew (East Carolina University, 2019-07-30)Collagens are a family of triple-helical structural proteins that are ubiquitous in vertebrates. Improper folding of collagen can lead to disorders such as osteogenesis imperfecta, or "brittle bone disease." There is ... -
The Thermodynamics of Cd(II) Binding to Human Cardiac Troponin C: Using Mutants to Determine the Location of Cd(II) Binding
Buddo, Katherine A. (East Carolina University, 2017-05-31)Historically, cadmium (Cd) has been used in many different applications from cadmium paint to nickel-cadmium batteries. However, Cd is a nonessential, naturally occurring toxic element due to its low excretion rate and ... -
Thermodynamic and spectroscopic studies of Cd²⁺ binding to the regulatory domain and full length human cardiac troponin C (HcTnC) : elucidating plausible Cd²⁺ binding sites
Fulcher, Lindsay Michelle (East Carolina University, 2015)Toxic metals such as cadmium (Cd²⁺) have been shown to bind to and interfere with various calcium (Ca²⁺) binding proteins including the regulatory protein cardiac troponin C (cTnC). Recent structural data has shown that ... -
Utilizing Isothermal Titration Calorimetry to Quantify the Thermodynamics of Cadmium Mimicry: A Comparison to Calcium
Johnson, Rachel Anne (East Carolina University, 2016-07-20)Isothermal titration calorimetry (ITC) is a powerful calorimetric method which can determine all thermodynamic parameters (K, [Delta]H, [Delta]G, and [Delta]S) for a binding event in a single experiment. More recently, ITC ...
