A Systematic Investigation Of The Effects Of Chain Length And Ionic Head Group On Perfluoroalkyl Acid Binding To Human Serum Albumin, Jake Ulrich
Honors Theses
Perfluoroalkyl acids (PFAAs) are industrial chemicals used in everyday products ranging from non-stick coatings to fire-fighting foam. PFAAs are contaminants of emerging concern (CECs) and are bioaccumulative, persistent and toxic. Unlike other CECs, PFAAs bioaccumulate in areas of high protein concentration, such as the kidneys, liver and blood; therefore, it is vital to study PFAA-protein interactions. Human Serum Albumin (HSA) is the model protein used for PFAA-protein studies because it is the most abundant protein in the human body and it binds and transports endogenous and exogenous ligands. Previously, researchers have investigated PFAA-HSA binding, but most of these studies have …
Prediction Of Metal Charge-Dependent Amide Hydrogen Exchange Rates For The Proteins Rubredoxin And Azurin, Stephen Scoglio
Prediction Of Metal Charge-Dependent Amide Hydrogen Exchange Rates For The Proteins Rubredoxin And Azurin, Stephen Scoglio
Honors Theses
Although it has been shown that the hydrogen exchange rates between the most slowly exchanging amide protons of a protein and the solvent can be used to predict the global thermodynamic stability of a protein, the great majority of amide hydrogens along the backbone of a protein exchange from either partially or fully folded conformations, and their rate of exchange strongly depends upon the environment in that folded state. We are examining the electrostatic and conformational dependence of the hydrogen exchange kinetics of Pseudomonas aeruginosa azurin, which can bind either the diamagnetic Cu(I) or Zn(II) in its active site and …
