The human glutathione S-transferases. Studies on the kinetic, stability and inhibition characteristics of the erythrocyte enzyme

Abstract Bromosulphophthalein and N -ethylmaleimide, inhibitors of glutathione S -transferase (EC 2.5.1.18, RX:glutathione R. transferase), have been used to identify variant forms of the erythrocyte enzyme. One ‘atypical’ sample was detected and was shown to have appreciably different kinetic and stability properties. These inhibitors may be useful in surveys of variation in this group of enzymes.
