A glutathione S-aryltransferase [EC 2.5.1.13 [EC] ] was purified to homogeneity from the liver of rhesus monkey. The purified enzyme had a molecular weight of about 55,000 as examined by gel filtration on a column of Sephadex G-100. Upon SDS-gel electrophoresis, it gave a single band corresponding to a molecular weight of about 25,000. These results indicate that the enzyme is composed of two subunits of an identical molecular weight.
