Both of these enzymes use L-arginine as substrate; iNOS (inducible NO sintase) produces NO (nitric oxide) (the most important leishmanicidal molecule) from L-arginine through two steps, whereas arginase catalyzes the hydrolysis of L-arginine into ornithine, the primary source of polyamines [ 51].
So environmental scientists Avner Vengosh and Laura Ruhl of the Nicholas School of the Environment at Duke University visited Tennessee in the months after the spill to collect samples of coal ash slurry, sediments, and water from various sites along the Emory and Clinch Rivers, which flow into the Tennessee River, the primary source of drinking water for some 410,000 Tennesseans.
