Cytosolic glutathione transferases of Proteus vulgaris were purified by affinity chromatography and characterized by two-dimensional gel electrophoresis. Four different subunits were identified, and each subunit contained a different molecular mass, ranging from 26.2 kDa to 28.5 kDa; a different pI value, ranging from 8.2 to 9.4; and a different amount of protein fraction, ranging from 10% to 56%. All four subunits existed as basic proteins (pI > 7.0). From these results, we concluded that multiple forms of glutathione transferase enzymes existed in Proteus vulgaris, and four different glutathione transferase subunits were separated by 2-D gel electrophoresis.
