The ability of three distinct types of human cytosolic glutathione transferase to catalyze the formation of leukotriene C4 from glutathione and leukotriene A4 has been demonstrated. The near-neutral transferase (mu) was the most efficient enzyme with Vmax= 180 nmol X min-1 X mg-1 and Km= 160 microM. The Vmax and Km values for the basic (alpha-epsilon) and the acidic (pi) transferases were 66 and 24 nmol X min-1 X mg-1 and 130 and 190 microM, respectively. The synthetic methyl ester derivative of leukotriene A4 was somewhat more active as a substrate for all the three forms of the enzyme.
