Nitric Oxide (NO) is an important regulator of numerous essential physiological processes like blood pressure, neurotransmission, insulin release, memory storage, and the immune response. In addition, NO is involved in a variety of serious pathophysiological processes, including septic shock, atherosclerosis, diabetes, as well as myocardial and cerebral ischemia. The biogenesis of NO is catalyzed by Nitric Oxide Synthase (NOS) enzymes. The long-term goal of our research program is to understand the regulation and mechanism of the NOS enzymes.
