Description
Arginase catalyzes the hydrolysis of arginine to ornithine and urea. At least two isoforms of mammalian arginase exist (types I and II) which differ in their tissue distribution, subcellular localization, immunologic crossreactivity and physiologic function. The type I isoform is a cytosolic enzyme and expressed predominantly in the liver as a component of the urea cycle. Inherited deficiency of this enzyme results in argininemia, an autosomal recessive disorder characterized by hyperammonemia. Arginase is involved in the nitric oxide (NO) pathway and immune cell arginine metabolism. It is fundamentally involved in cancer, inflammation, infections, fibrotic diseases, neurobiology, pregnancy and immune regulation in general.
