  • Title: Purification and properties of arginase of rat kidney.
    Author: Kaysen GA, Strecker HJ.
    Journal: Biochem J; 1973 Aug; 133(4):779-88. PubMed ID: 4748833.
    Abstract:
    l-Arginase from rat kidney was partially purified and some properties were compared with those of l-arginase of rat liver. The kidney enzyme was firmly bound to the mitochondrial fraction and after solubilization required arginine or an unknown factor in tissue extracts for stabilization after dialysis. The two enzymes differed also in stability with respect to acetone treatment, heating or freezing. In further contrast with liver arginase, arginase from kidney was not adsorbed to CM-cellulose at pH7.5 and its activity was not increased by incubation with Mn(2+). Other differences were seen in relative specificities for substrates, ratio of hydrolysis rates with high and low concentrations of arginine and effects of certain inhibitors. Antisera prepared to pure liver arginase did not cross-react with partially purified kidney arginase.
