摘要: Hydrogen sulfide (H(2)S) has been recognized as a smooth muscle relaxant. Cystathionine gamma-lyase, which is localized to muscle, thought be the major H(2)S-producing enzyme in thoracic aorta. Here we show that 3-mercaptopyruvate sulfurtransferase (3MST) and cysteine aminotransferase (CAT) are vascular endothelium aorta produce H(2)S. Both 3MST CAT were endothelium. Lysates of endothelial cells produced H(2)S from alpha-ketoglutarate. The present study provides new insight into production release relaxant
