Brief description Biochemical properties of S-nitroso-myoglobin and its role in regulating nitric oxide bio-availability. Nitric oxide (NO) stimulates blood vessel dilation. Vessel dilation is essential to maintaining blood pressure. Altered NO-regulation leads to vessel dysfunction. Within blood vessels, myoglobin regulates NO concentrations through oxidation and binding reactions. In contrast, S-nitroso-myoglobin represents a novel source of NO in humans. The goal of this study is to expand the knowledge on NO-regulation by myoglobin through determining S-nitroso-myoglobin's - chemical stability, rates of formation and decay, concentration in human vessels and whether it can cause blood vessel dilation similar to authentic NO. Such novel data represents a major fundamental advance in understanding the role of myoglobin in NO-homeostasis.
