A rat-tissue aminotransferase acting on L-tyrosine O-sulphate

F A Rose et al. Biochem J. 1966 Jan.

Abstract

1. Rat tissues have been shown to possess an aminotransferase that is active towards l-tyrosine O-sulphate and dependent on 2-oxoglutarate and pyridoxal phosphate. 2. Kidney, liver and pancreas have the greatest activity and the enzyme is localized mainly in the mitochondrial fraction in the liver and kidney cell. 3. The enzyme was shown to be distinct from l-tyrosine-2-oxoglutarate aminotransferase but its true identity was not established. 4. A procedure for the assay of the enzyme in crude tissue preparations was developed.
