Binding Affinity Of Flavins To The Dehydrogenase Domain Of Spnox, Quinesha Williams

Master of Science in Chemical Sciences Theses

NADPH oxidases (NOX’s) are enzymes that catalyze the production of superoxide through single electron transfer. This superoxide production leads to the production of other reactive oxygen species (ROS). ROS affect many metabolic processes throughout the body that can cause several different diseases, making this an ideal target for drug discovery. The general structure of NOX contains a transmembrane (TM) domain and a dehydrogenase (DH) domain connected by a linker. The DH domain contains binding sites for FAD and NADPH/NADH that both participate in the electron transfer necessary for producing superoxide. Structural information of NOX’s is still relatively new to the …
